The `_register_theme_block_patterns` function imposed a significant resource overhead. This issue primarily stems from themes, such as TT4, that register a substantial number of block patterns. These patterns necessitate numerous file operations, including file lookups, file reading into memory, and related processes. To provide an overview, the _register_theme_block_patterns function performed the following file operations:
- is_dir
- is_readable
- file_exists
- glob
- file_get_contents (utilized via get_file_data)
To address these issues, caching using a transient has been added to a new function call `_wp_get_block_patterns`. If theme development mode is disabled and theme exists, the block patterns are saved in a transient cache. This cache is used all requests after that, saving file lookups and reading files into memory. Cache invalidation is done, when themes are switched, deleted or updated. Meaning that block patterns are not stored in the cache incorrectly.

This removes ignore annotations which are ignoring an error which would not be thrown for that code.
Includes tidying up the format of the ignore annotation:
* Customary one space between the `//` and the start of the comment.
* There should be no spaces in the comma-separated sniff list.

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'`.

Quoting poena from the ticket: "[...] To make it easier for users to find these

already been built to include the new category, with the slug "footer" [to]

In 6.0 there is now a functionality that allows to register selected remote patterns (from the Pattern Directory) via `theme.json`. However, it requires to fully enable all core and remote patterns. This can be a blocker for user adoption.
Many theme authors want to have all core and remote patterns disabled by default using `remove_theme_support( 'core-block-patterns' )`. This changeset ensures they are serving only patterns relevant to their theme.
This changeset removes theme support check from the function that registers remote patterns specified in `theme.json`. This allows theme authors to disable core patterns but then selectively register the ones they want from the Pattern Directory. If a theme author intentionally specifies patterns in `theme.json`, they probably intend for them to be present in the pattern inserter and the check is not required.
This change will make the Pattern Directory more appealing/usable from the theme author's perspective.

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.

Because the `__()` translation function was used here, the Query block pattern category string is not translatable. `_x()` is the correct function here as that passes the second parameter as context and not text domain.
