These changes prevent a flash of style updates for applied block style variations when the global styles data is loaded into the block editor. This is done by preloading the global styles REST API paths which also brings the post and site editors further into line.

Adds `wp_theme_has_theme_json()` for public consumption, to replace the private internal Core-only `WP_Theme_JSON_Resolver::theme_has_support()` method. This new global function checks if a theme or its parent has a `theme.json` file.
For performance, results are cached as an integer `1` or `0` in the `'theme_json'` group with `'wp_theme_has_theme_json'` key. This is a non-persistent cache. Why? To make the derived data from `theme.json` is always fresh from the potential modifications done via hooks that can use dynamic data (modify the stylesheet depending on some option, settings depending on user permissions, etc.).
Also adds a new public function `wp_clean_theme_json_cache()` to clear the cache on `'switch_theme'` and `start_previewing_theme'`.

This patch optimizes preload paths in post and site editors so that they match the real requests:
- Remove the `/` preload as the payload is very big and the response is not needed on any critical path.
- Modify the preloaded path for `/wp/v2/taxonomies` so that it corresponds to what `loadTaxonomyEntities` requests. After Gutenberg PR 37685 was merged to core, these preloads need to be modified to use `context=view` instead of `context=edit`.
- Modify the `/wp/v2/users/me path` so that it matches the real request (no query params).
- Add a preload of `/wp/v2/settings` because it is requested on critical path (editor boot). Site editor already preloads this, the changeset is only adding it to the post editor.
This is related to Gutenberg PR 39256 which introduces compatibility code to modify the preload paths with a filter, when the Gutenberg plugin is active.

Remote block patterns from wp.org were to be loaded through a callback hooked into the `current_screen` filter. Within 2 callbacks, i.e. `_load_remote_featured_patterns()` and `_load_remote_block_patterns()`, a guard clause bailed out early if the `$current_screen->is_block_editor` is `false`.
However, the `current_screen` filter is unreliable to detect the block editor. Why? In the block and Site Editor screens, `$current_scren->is_block_editor` is not set until after the filter is executed. Whoopsie.
This commit no longer uses the `current_screen` filter. Instead, it explicitly loads the remote block patterns by invoking both private functions (now not callbacks) directly in the screen files for the block and site editor screens.
With this change, passing `WP_Screen` object into these functions is no longer needed. As the `_load_remote_block_patterns()` function was introduced in 5.8.0, its function parameter is now deprecated and the guard clause retained for backwards compatibility.

Previously, the block editor initialization always provided "title", "content" and "excerpt" initial edits in the `initializeEditor` call even though these properties might not be supported by the current post type being edited. This leads to a bug in the post editor where as soon as one would open a "new post", the editor considers the content "dirty", meaning changes are applied and it is not possible to leave the editor without encountering an "unsaved changes" notice.
This change updates the `$initial_edits` variable declaration to only provide the properties that are supported by the current post type.

While a custom post type can define a custom route by using the `rest_base` argument, a namespace of `wp/v2` was assumed. This commit introduces support for a `rest_namespace` argument.
A new `rest_get_route_for_post_type_items` function has been introduced and the `rest_get_route_for_post` function updated to facilitate getting the correct route for custom post types.
While the WordPress Core Block Editor bootstrap code has been updated to use these API functions, for maximum compatibility sticking with the default `wp/v2` namespace is recommended until the API functions see wider use.

Previously, the original "404" template key was lost when "Default template" is merged into the available templates array, as the `array_merge()` function renumbers numeric keys. Later, when we merge templates on the client side, this caused duplicate "404" templates to appear in the dropdown.
By replacing the `array_merge()` call with `array_replace()`, we make sure to keep the original numeric keys.
