By default, block themes should have a few theme supports enabled:
* `post-thumbnails`
* `responsive-embeds`
* `editor-styles`
* `html5` for `comment-form`, `comment-list`, `style`, `script`
* `automatic-feed-links`
They should also load core block assets only when the blocks are rendered. This commit adds the associated tests.

This commit renames the following method and function to better represent block theme terminology:
* `WP_Theme::is_block_based()` to `WP_Theme::is_block_theme()`
* `wp_is_block_template_theme()` to `wp_is_block_theme()`
It also changes `wp_is_block_theme()` to be a helper wrapper (sugar syntax) for `wp_get_theme()->is_block_theme();`. Why? To ensure both the method and function behave the same, to help Gutenberg maintain WordPress cross-version compatibility, and to make it less cumbersome to port changes from Gutenberg to Core.

These checks were added in [51193] and [51197] as a temporary measure to prevent a site owner from activating a Full Site Editing theme when Gutenberg plugin was not active.
Because Core only had partial support for the features required for FSE, the front end of the site would display a white screen or error message to visitors. Unless the site owner visited the front end, there would be no indication that there was a problem.
Since 5.9 will include the remaining features required for FSE, these checks can be removed.

This change adds a filter inside of the `get_header_image_tag()` function allowing developers to filter the attributes of the header image HTML tag before they are escaped, concatenated, and returned.
Before this change, it was not possible to externally and preemptively intercept this array of attributes. After this change, these attributes can now be easily filtered, matching it nicely to the `wp_get_attachment_image_attributes` hook.

The original name `retrieve_widgets()` was unclear as it suggested it was a getter, i.e. getting the widgets. This function does more than get: finds orphaned widgets, assigns them to the inactive sidebar, and updates the database.
The new name is `sync_registered_widgets()` which better represents what happens when this function is invoked.
The original `retrieve_widgets()` function is soft deprecated to avoid unnecessary code churn downstream for developers that support more than the latest version of WordPress.

This avoids a "Cannot access offset of type string on string" fatal error in `set_theme_mod()` on PHP 8 if the `theme_mods_$theme_slug` option has an incorrect value, e.g. an empty string instead of an array.
With this change, `set_theme_mod()` should be able to resolve the issue by saving a correct value.

This better aligns with developer expectations, as `add_theme_support()` and `remove_theme_support()` are meant to be called within functions attached to the `after_setup_theme` hook.
This also adds the `widgets-block-editor` feature to the docblock for `add_theme_support()`.

When a theme that uses the Full Site Editing feature is activated and the Gutenberg plugin is not present, the site will currently show a text notice on the front end. The user is not made aware of this unless they visit the front end of their site.
This adds a check that will prevent a theme from being activated when the `full-site-editing` tag is present in the theme’s `style.css` header and the Gutenberg plugin is not active to prevent this scenario.
These checks can be removed once Full Site Editing is completely merged into Core.

This affects:
* `validate_plugin_requirements()`
* `validate_theme_requirements()`
Historically, the `Requires PHP` header was introduced in #meta2952 for the Plugin Directory first, so at the time it made sense to have it defined in the same place as `Requires at least`, which only existed in `readme.txt`.
Since parsing of PHP and WordPress requirements was later added to WordPress core, the core should retrieve all the necessary data from the main plugin or theme file and not from `readme.txt`, which only contains the data meant for the Plugin or Theme Directory.
The recommended place for `Requires PHP` and `Requires at least` headers is as follows:
* The plugin's main PHP file
* The theme's `style.css` file
The place for the `Tested up to` header remains in `readme.txt` for the time being, as it's not used by WordPress core.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast

Currently themes can declare support for a given feature by using add_theme_support(). This commit adds a register_theme_feature() API that allows plugins and WordPress Core to declare a list of available features that themes can support.

“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”
With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).
Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.
Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.
