Blocks: Implement automatic block insertion into Block Hooks. Block Hooks allow a third-party block to specify a position relative to a given block into which it will then be automatically inserted (e.g. a "Like" button block can ask to be inserted after the Post Content block, or an eCommerce shopping cart block can ask to be inserted after the Navigation block). The underlying idea is to provide an extensibility mechanism for Block Themes, in analogy to WordPress' [https://developer.wordpress.org/plugins/hooks/ Hooks] concept that has allowed extending Classic Themes through filters and actions. The two core tenets for Block Hooks are: 1. Insertion into the frontend should happen right after a plugin containing a hooked block is activated (i.e. the user isn't required to insert the block manually in the editor first); similarly, disabling the plugin should remove the hooked block from the frontend. 2. The user has the ultimate power to customize that automatic insertion: The hooked block is also visible in the editor, and the user's decision to persist, dismiss (i.e. remove), customize, or move it will be respected (and reflected on the frontend). To account for both tenets, the **tradeoff** was made to limit automatic block insertion to unmodified templates (and template parts, respectively). The reason for this is that the simplest way of storing the information whether a block has been persisted to (or dismissed from) a given template (or part) is right in the template markup. To accommodate for that tradeoff, [https://github.com/WordPress/gutenberg/pull/52969 UI controls (toggles)] are being added to increase visibility of hooked blocks, and to allow for their later insertion into templates (or parts) that already have been modified by the user. For hooked blocks to appear both in the frontend and in the editor (see tenet number 2), they need to be inserted into both the frontend markup and the REST API (templates and patterns endpoints) equally. As a consequence, this means that automatic insertion couldn't (only) be implemented at block ''render'' stage, as for the editor, the ''serialized'' (but ''unrendered'') markup needs to be modified. Furthermore, hooked blocks also have to be inserted into block patterns. Since practically no filters exist for the patterns registry, this has to be done in the registry's `get_registered` and `get_all_registered` methods. Props gziolo. Fixes #59313.

Block Hooks: Store ignored hooked blocks metadata in anchor block.

This is achieved by storing all known blocks hooked to a given anchor block in the `metadata` attribute on that anchor block; specifically in a field called `ignoredHookedBlocks` inside of the `metadata`. Hooked blocks are only rendered on the frontend if they're absent from that field; OTOH, they're injected into that field (via the REST API) when first loaded in the editor. This simple logic guarantees that once a user modifies a given layout, those changes are respected on the frontend; yet if a plugin that includes a hooked block is activated after those modifications have taken place, the hooked block will be rendered on the frontend. This new technique supplants the one previously used (i.e. rendering hooked blocks on the frontend only if a layout doesn't have any modifications) in a rather direct way. Note that this changeset only introduces the new metadata field and relevant logic; it does not yet enable hooked block insertion into modified layouts.

Block Hooks: Allow traversal callbacks to modify parent block. The callbacks returned by `make_before_block_visitor` and `make_after_block_visitor`, respectively, (which are passed as arguments to `traverse_and_serialize_block(s)`) currently accept three arguments, all of which are block arrays (i.e. with properties `blockName`, `attrs`, etc.): - A ''reference'' to the block they're currently visiting, `&$block`; - the block's `$parent_block`; and - the `$prev`ious block (for `make_before_block_visitor`), or the `$next` block (for `make_after_block_visitor`), respectively. Those arguments are passed to the "block visitor" callbacks by `traverse_and_serialize_block(s)` during traversal. The block that the callback is currently visiting is passed ''by reference'' to allow modifying it, which is e.g. used to inject the `theme` attribute into Template Part blocks. One major limitation of Block Hooks is that they currently only work with templates, parts, and patterns that ''don't have any user modifications'' (i.e. that come straight from the corresponding theme files, rather than from the database). For WordPress 6.5, it is planned to change that to make Block Hooks work for templates, parts, and patterns that ''do'' have user modifications: #59646. This will be implemented by storing an attribute on the "anchor" block. While working on that feature, it was found that the aforementioned callbacks will need to modify not only the currently visited `$block`, but also the `$parent_block` -- i.e. that the latter argument needs to be passed by reference as well. This is consistent with the requirement of adding an attribute to an anchor block, as it's not only the currently visited block that can serve as an anchor block (in the case of `before` or `after` sibling insertion), but also its parent (for `first_child` and `last_child` insertion). If the `$parent_block` argument were to be changed to become a reference in a later WordPress version, this could be considered a backwards-compatibility breaking change. For this reason, this change is instead proposed for 6.4 already, which is the cycle during which the relevant functions were first introduced. This should have no impact on existing code, since nothing currently relies on `$parent_block` remaining unmodified by the respective callback, nor is anything currently modifying that argument.

Blocks: Implement automatic block insertion into Block Hooks. Block Hooks allow a third-party block to specify a position relative to a given block into which it will then be automatically inserted (e.g. a "Like" button block can ask to be inserted after the Post Content block, or an eCommerce shopping cart block can ask to be inserted after the Navigation block). The underlying idea is to provide an extensibility mechanism for Block Themes, in analogy to WordPress' [https://developer.wordpress.org/plugins/hooks/ Hooks] concept that has allowed extending Classic Themes through filters and actions. The two core tenets for Block Hooks are: 1. Insertion into the frontend should happen right after a plugin containing a hooked block is activated (i.e. the user isn't required to insert the block manually in the editor first); similarly, disabling the plugin should remove the hooked block from the frontend. 2. The user has the ultimate power to customize that automatic insertion: The hooked block is also visible in the editor, and the user's decision to persist, dismiss (i.e. remove), customize, or move it will be respected (and reflected on the frontend). To account for both tenets, the **tradeoff** was made to limit automatic block insertion to unmodified templates (and template parts, respectively).

Block Hooks: Allow traversal callbacks to modify parent block. The callbacks returned by `make_before_block_visitor` and `make_after_block_visitor`, respectively, (which are passed as arguments to `traverse_and_serialize_block(s)`) currently accept three arguments, all of which are block arrays (i.e. with properties `blockName`, `attrs`, etc.): - A ''reference'' to the block they're currently visiting, `&$block`; - the block's `$parent_block`; and - the `$prev`ious block (for `make_before_block_visitor`), or the `$next` block (for `make_after_block_visitor`), respectively. Those arguments are passed to the "block visitor" callbacks by `traverse_and_serialize_block(s)` during traversal. The block that the callback is currently visiting is passed ''by reference'' to allow modifying it, which is e.g. used to inject the `theme` attribute into Template Part blocks. One major limitation of Block Hooks is that they currently only work with templates, parts, and patterns that ''don't have any user modifications'' (i.e. that come straight from the corresponding theme files, rather than from the database). For WordPress 6.5, it is planned to change that to make Block Hooks work for templates, parts, and patterns that ''do'' have user modifications: #59646. This will be implemented by storing an attribute on the "anchor" block. While working on that feature, it was found that the aforementioned callbacks will need to modify not only the currently visited `$block`, but also the `$parent_block` -- i.e. that the latter argument needs to be passed by reference as well. This is consistent with the requirement of adding an attribute to an anchor block, as it's not only the currently visited block that can serve as an anchor block (in the case of `before` or `after` sibling insertion), but also its parent (for `first_child` and `last_child` insertion). If the `$parent_block` argument were to be changed to become a reference in a later WordPress version, this could be considered a backwards-compatibility breaking change. For this reason, this change is instead proposed for 6.4 already, which is the cycle during which the relevant functions were first introduced. This should have no impact on existing code, since nothing currently relies on `$parent_block` remaining unmodified by the respective callback, nor is anything currently modifying that argument.

Blocks: Implement automatic block insertion into Block Hooks.

The user has the ultimate power to customize that automatic insertion: The hooked block is also visible in the editor, and the user's decision to persist, dismiss (i.e. remove), customize, or move it will be respected (and reflected on the frontend). To account for both tenets, the **tradeoff** was made to limit automatic block insertion to unmodified templates (and template parts, respectively). The reason for this is that the simplest way of storing the information whether a block has been persisted to (or dismissed from) a given template (or part) is right in the template markup. To accommodate for that tradeoff, [https://github.com/WordPress/gutenberg/pull/52969 UI controls (toggles)] are being added to increase visibility of hooked blocks, and to allow for their later insertion into templates (or parts) that already have been modified by the user. For hooked blocks to appear both in the frontend and in the editor (see tenet number 2), they need to be inserted into both the frontend markup and the REST API (templates and patterns endpoints) equally. As a consequence, this means that automatic insertion couldn't (only) be implemented at block ''render'' stage, as for the editor, the ''serialized'' (but ''unrendered'') markup needs to be modified.

Block Hooks: Allow traversal callbacks to modify parent block. The callbacks returned by `make_before_block_visitor` and `make_after_block_visitor`, respectively, (which are passed as arguments to `traverse_and_serialize_block(s)`) currently accept three arguments, all of which are block arrays (i.e. with properties `blockName`, `attrs`, etc.): - A ''reference'' to the block they're currently visiting, `&$block`; - the block's `$parent_block`; and - the `$prev`ious block (for `make_before_block_visitor`), or the `$next` block (for `make_after_block_visitor`), respectively. Those arguments are passed to the "block visitor" callbacks by `traverse_and_serialize_block(s)` during traversal. The block that the callback is currently visiting is passed ''by reference'' to allow modifying it, which is e.g. used to inject the `theme` attribute into Template Part blocks. One major limitation of Block Hooks is that they currently only work with templates, parts, and patterns that ''don't have any user modifications'' (i.e. that come straight from the corresponding theme files, rather than from the database). For WordPress 6.5, it is planned to change that to make Block Hooks work for templates, parts, and patterns that ''do'' have user modifications: #59646. This will be implemented by storing an attribute on the "anchor" block. While working on that feature, it was found that the aforementioned callbacks will need to modify not only the currently visited `$block`, but also the `$parent_block` -- i.e. that the latter argument needs to be passed by reference as well. This is consistent with the requirement of adding an attribute to an anchor block, as it's not only the currently visited block that can serve as an anchor block (in the case of `before` or `after` sibling insertion), but also its parent (for `first_child` and `last_child` insertion). If the `$parent_block` argument were to be changed to become a reference in a later WordPress version, this could be considered a backwards-compatibility breaking change. For this reason, this change is instead proposed for 6.4 already, which is the cycle during which the relevant functions were first introduced. This should have no impact on existing code, since nothing currently relies on `$parent_block` remaining unmodified by the respective callback, nor is anything currently modifying that argument.

Block Hooks: Allow traversal callbacks to modify parent block. The callbacks returned by `make_before_block_visitor` and `make_after_block_visitor`, respectively, (which are passed as arguments to `traverse_and_serialize_block(s)`) currently accept three arguments, all of which are block arrays (i.e. with properties `blockName`, `attrs`, etc.): - A ''reference'' to the block they're currently visiting, `&$block`; - the block's `$parent_block`; and - the `$prev`ious block (for `make_before_block_visitor`), or the `$next` block (for `make_after_block_visitor`), respectively. Those arguments are passed to the "block visitor" callbacks by `traverse_and_serialize_block(s)` during traversal. The block that the callback is currently visiting is passed ''by reference'' to allow modifying it, which is e.g. used to inject the `theme` attribute into Template Part blocks. One major limitation of Block Hooks is that they currently only work with templates, parts, and patterns that ''don't have any user modifications'' (i.e. that come straight from the corresponding theme files, rather than from the database). For WordPress 6.5, it is planned to change that to make Block Hooks work for templates, parts, and patterns that ''do'' have user modifications: #59646. This will be implemented by storing an attribute on the "anchor" block. While working on that feature, it was found that the aforementioned callbacks will need to modify not only the currently visited `$block`, but also the `$parent_block` -- i.e. that the latter argument needs to be passed by reference as well. This is consistent with the requirement of adding an attribute to an anchor block, as it's not only the currently visited block that can serve as an anchor block (in the case of `before` or `after` sibling insertion), but also its parent (for `first_child` and `last_child` insertion). If the `$parent_block` argument were to be changed to become a reference in a later WordPress version, this could be considered a backwards-compatibility breaking change. For this reason, this change is instead proposed for 6.4 already, which is the cycle during which the relevant functions were first introduced.

Code Modernization: Rename parameters that use reserved keywords in `wp-includes/blocks.php`. While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names. This commit renames the `$default` parameter to `$default_value` in `block_has_support()`.
