`str_starts_with()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins with the given substring (needle).
WordPress core includes a polyfill for `str_starts_with()` on PHP < 8.0 as of WordPress 5.9.
This commit replaces `0 === strpos( ... )` with `str_starts_with()` in core files, making the code more readable and consistent, as well as improving performance.
While `strpos()` is slightly faster than the polyfill on PHP < 8.0, `str_starts_with()` is noticeably faster on PHP 8.0+, as it is optimized to avoid unnecessarily searching along the whole haystack if it does not find the needle.

Removes the `WP_Error` code for `'Invalid user ID.'`. Why?
tl;dr
This branch will never be entered as the `$user` will never be falsey.
Longer reasoning:
[39954] introduced `WP_REST_Users_Controller::get_user()` method to encapsulate getting the user and handling the `'Invalid user ID.'` `WP_Error`. It replaced `get_userdata()` in `WP_REST_Users_Controller::update_item()` but left the existing `'Invalid user ID.'` `WP_Error` introduced in [38832].
The code removed in this changeset will never be reached because `$user` will never be falsey. Rather, `WP_REST_Users_Controller::get_user()` will always return an instance of `WP_Error` or `WP_User`.
Could the user's ID be falsey?
No. Why? `WP_REST_Users_Controller::get_user()` checks that the user exists, which checks if the ID is falsey.
Therefore, the code can safely be removed.

When switching to a block theme, classic sidebars were orphaned and their widgets remapping to the `'wp_inactive_widgets'` sidebar . This changeset preserves the sidebars and their widgets, providing a migration path to a block theme without losing the widgets.
Classic sidebars are now:
* Stored in a new theme mod called `'wp_classic_sidebars'`;
* Restored to the `$wp_registered_sidebars` global variable when the `'widgets_init'` action fires (via a new internal function called `_wp_block_theme_register_classic_sidebars()`);
* And marked as `'inactive'` when interacting with sidebars REST API endpoint.

This changeset introduces functions `wp_get_global_styles_custom_css()` and `wp_enqueue_global_styles_custom_css()`, which allow accessing and enqueuing custom CSS added via global styles.
Custom CSS via global styles is handled separately from custom CSS via the Customizer. If a site uses both features, the custom CSS from both sources will be loaded. The global styles custom CSS is then loaded after the Customizer custom CSS, so if there are any conflicts between the rules, the global styles take precedence.
Similarly to e.g. [55185], the result is cached in a non-persistent cache, except when `WP_DEBUG` is on to avoid interrupting the theme developer's workflow.

In [53874] the optional `$locale` parameter was added to `load_textdomain()`. While most `load_textdomain()` calls in core were were updated, some were missed. Passing the original locale avoids the need to call `determine_locale()` by `load_textdomain()` which is used as a fallback.

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`.

This changeset fixes a warning where `strip_tags()` expected its first parameter to be a string rather than an array. It contains the following changes:
- Removal of sanitize_callback to allow the REST API to handle the validation natively, this also causes the proper error to be output for `?slug[0][1]=2` that it's an invalid value.
- Ensure that `wp_parse_list()` only returns a single-dimensioned array, even if passed a multi-dimension array, which fits the functions expected use case and resolves warnings in code that expects the function to return a single-dimensioned array.

When calling `register_rest_route()`, the `args` parameter for a route should be an array of arrays. However, some plugins/themes have passed an array of strings or key-value pairs which produces a PHP warning when `array_intersect_key` is used to filter the array keys based on an allowed list of schema keywords.
This change adds a check of the `args` parameter to ensure it's an array of arrays, presenting a `_doing_it_wrong` if any element of `args` is not an array and restructuring to an array of arrays. This change also adds a unit test for the incorrect usage described above, expecting that a `_doing_it_wrong` is produced.

Not all requests are accompanied by a `$request['email']`. This leads to a PHP 8.1 "passing null to non-nullable" deprecation notice when the `WP_REST_Users_Controller::update_item()` method passes a `null` email address onto `email_exists()`, which eventually reached the `WP_User::get_data_by()` method where things go wrong.
In the next condition in the code of the `WP_REST_Users_Controller::update_item()` method - `if ( $owner_id && $owner_id !== $id )` - you can see that the code already takes this into account as it will not throw a `WP_Error` if `$owner_id` is falsey.
`WP_User::get_data_by()` returns `false` for a failed field request. The other functions through which the return value is passed through, do the same.
So, by setting a default value for `$owner_id` of `false` and only checking `email_exists()` when there is an email to check, the "passing null to non-nullable" deprecation notice is bypassed without breaking BC.
Fixes a whole slew of test errors along the lines of:

This commit improves site editor templates by:
* Adds a post meta `is_wp_suggestion` to templates created from the site editor.
Why? To differentiate the templates created from the post editor in the Template panel in inspector controls and the templates suggested in site editor.
See [https://github.com/WordPress/gutenberg/pull/41387 Gutenberg PR 41387] for more details.
* Expands the template types that can be added to the site editor to include single custom post type and specific posts templates.
See [https://github.com/WordPress/gutenberg/pull/41189 Gutenberg PR 41189] for more details.
* Adds fallback template content on creation in site editor:
* Introduces `get_template_hierarchy()` to get the template hierarchy for a given template slug to be created.
* Adds a `lookup` route to `WP_REST_Templates_Controller` to get the fallback template content.
See [https://github.com/WordPress/gutenberg/pull/42520 Gutenberg PR 42520] for more details.
* Fixes a typo in default category template's description within `get_default_block_template_types()`.
See [https://github.com/WordPress/gutenberg/pull/42586 Gutenberg PR 42586] for more details.
* Changes field checks from `in_array()` to `rest_is_field_included()` in `WP_REST_Post_Types_Controller`.
* Adds an `icon` field to `WP_REST_Post_Types_Controller`
