c0ed2c6f06 Editor: Merge uses_context defined by block bindings sources with block types
Adds logic that fixes the limitation for souces by allowing merging the `uses_context` defined by block bindings sources into supported block types. Each source defines the context it needs and it is added to the block types that are using the block bindings API.

Fixes #60525.

Syncing changes from the Gutenberg plugin: https://github.com/WordPress/gutenberg/pull/57437.

Scripts and styles can be registered for blocks via `block.json` metadata. There is now a Modules API, but was no way to register or associate module assets with blocks via `block.json`.

5d2bccd66d Editor: Support deferred block variation initialization on the server.
When registering blocks on the server using `register_block_type()` or similar functions, a set of block type variations can also be registered. However, in some cases building this variation data during block registration can be an expensive process, which is not needed in most contexts. 

To address this problem, this adds support to the `WP_Block_Type` object for a new property, `variation_callback`, which can be used to register a callback for building variation data only when the block variations data is needed. The `WP_Block_Type::variations` property has been changed to a private property that is now accessed through the magic `__get()` method. The magic getter makes use of a new public method, `WP_Block_Type::get_variations` which will build variations from a registered callback if variations have not already been built.

This fixes the currently flagged `WordPress.PHP.StrictInArray.MissingTrueStrict` issues:
* `Not using strict comparison for in_array; supply true for third argument.`

These all do comparisons with strings, so all the more reason why it is imperative that a strict comparison is used.

ca3cfae579 Blocks: Allow arrays for deprecated asset types in block registration.
In `register_block_type`, continue to allow passing arrays as the `editor_script`, `script`, `view_script`, `editor_style`, and `style` arguments. Note that those fields were soft-deprecated in favor of their `_handles` counterparts in [54155], which would allow specifying multiple items. At the same time, the deprecated fields were limited to `string` or `null`.

However, this broke existing code that passed an array as one of those arguments. For backwards compatibility, this change thus restores the previous behavior. It is implemented in `WP_Block_Type` as a pair of `__get()` and `__set()` methods that wrap around the corresponding `_handles` members, which are arrays of strings.

It also affects the REST API endpoint for block types. The latter’s schema has never allowed for anything other than `string` or `null` for any of those fields. For this reason, it now returns the first element of the array stored in the corresponding `_handles` member in `WP_Block_Type`.

714e57b2fc Blocks: Allow registering multiple items for all supported asset types
Follow-up #54337, [52069]. Part of https://github.com/WordPress/gutenberg/issues/41236. More details in https://github.com/WordPress/gutenberg/issues/33542.

Allow passing more than one script per block for `editorScript`, `script`, and `viewScript` fields in the `block.json` metadata file. This aligns with the previously added changes for `style` and `editorStyle` fields.

This change impacts the `WP_Block_Type` class and the REST API endpoint for block types. To ensure backward compatibiliy old names were soft deprecated in favor of new fields that work with array values and have `_handles` suffix.

c03305852e Code Modernization: Add AllowDynamicProperties attribute to all (parent) classes.
Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.

There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.

Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.

To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.

The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
 - If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
 - If it extends a PHP native class: add the attribute.
 - If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.

Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.

This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.

327852393a Build: Split packages and blocks to their webpack configs
It aligns with the changes proposed added in Gutenberg: https://github.com/WordPress/gutenberg/pull/33293.

The idea here is to split the growing webpack config into two parts: blocks and  packages.

We need to add handling for JavaScript files that are going to be used with blocks on the frontend. They didn't work quite well with the current setup for entry points created for packages.

As part of the effort, it adds support for `viewScript` in `block.json` metadata file that is later translated to `$view_script` in `WP_Block_Type` class and exposed as `view_script` from the REST API endpoint for block types.

eec4c743fa Blocks: Update default value for some fields in WP_Block_Type
Related to the issue with default values for the blocks registered on the server. By using null for some fields we can treat them as undefined on the client.

bc9dfcfeb1 REST API: Preserve unknown, respect null in server-side block rendering.
- Skips validation where there is no attribute definition, but keeps the attribute value. Previously, the attribute would be omitted from the attributes passed to `render_callback`. Notably, this resolves an issue where `render_callback` cannot receive a block's `align` and `customClassName` attribute values, since these are defined as a client-side filter.
- Validates `null` as a proper value in its own right. Previously, a client implementation of a block could track `{“attribute":null}` as an explicitly empty value, and the server would wrongly initiate defaulting behavior. The new behavior will now only populate a default value if the attribute is not defined at all, including when unset in its being invalid per the attribute schema.
