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.

For performance, a static variable is added to `wp_theme_has_theme_json()` to cache the boolean result of determining if a theme (or its parent) has a `theme.json` file.
This cache avoids the overhead of calling `get_stylesheet_directory()` and `get_template_directory()` each time `wp_theme_has_theme_json()` is invoked.
The cache is lean, non-persistent, and encapsulated within the function (i.e. function scope and not available externally).
The cache is ignored when:
* `WP_DEBUG` is on to avoid interrupting theme developer's workflow and for extender automated test suites.
* `WP_RUN_CORE_TESTS` is on to ensure each Core test exercises the checking code.

Calls to `wp-admin/load-styles.php` do not include the loading of `wp_cache_*()` functions. With [55086], this caused a fatal error:
{{{
Fatal error: Uncaught Error: Call to undefined function wp_cache_get() in /wp-includes/global-styles-and-settings.php on line 285
}}}
In some production and local environments running `trunk`, the admin area looked broken as the styling was not loaded as there were no HTTP requests.
This commit reverts the caching from [55086] to restore sites running `trunk` until a solution is found.

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 changeset updates the blocks origin name from core to blocks and adds it to the list of valid origins for `theme.json`.
(See the original fix in [https://github.com//pull/3319 Gutenberg's PR 44363]).
Why?
- This new origin was missing from the list.
- The `core` name is not reflective of what it does, as this data origin is related to block styles, whether they come with WordPress or third-party blocks.
- The existing filter for this piece of data is called `theme_json_blocks`, to reflect it filters "block" data.
- Though `core` origin was used in the past for `default`, this commit reverts it. Why? It was confusing. The goal is to use names that communicate what part of the pipeline are processing (`default > blocks > theme > custom`).
How?
- Renames the string, from `core` to `blocks`.
- Adds `blocks` to the list of valid origins.
- Verifies that the `$theme_json->get_stylesheet()` call uses the proper `$origins` at all times.

Notes:
* It doesn't entirely port over PR 40875 — the remaining PHP changes for that PR will be explored in a separate PR targeting `layout.php`.
* [54159] was reverted in [54160] due to PHPUnit test failures for tests added by the commit. Later, tests passed when applied on top of `trunk`. There were various outages today of upstream `wp-env` dependencies, which likely were the root cause of the earlier failures. For historical tracking and to make sure, recommitting [54159] but instead on top of current `trunk`. See PR 3205 for more details.
* Giving additional props for those who did a deep dive investigation into the failed tests.
