Comment:

 In [changeset:"56979" 56979]:
 {{{
 #!CommitTicketReference repository="" revision="56979"
 Themes: Make caches for block patterns clearable.

 In [56765], theme block pattern files were cached to a transient as a
 performance enhancement. However, transients are not easily clearable when
 caches are flushed on environments not using a persistent cache, which can
 lead to errors if the theme files are renamed, edited, or moved.

 This changes the caching mechanism to use `wp_cache_set()` instead, and
 caches these values to the global group so they are still persistent on
 environments using an object cache, and will be cleared by a cache flush.

 In addition, the helper `_wp_get_block_patterns` has been moved
 `WP_Theme::get_block_patterns` for consistency with other block related
 theme methods and cache helpers for these values,
 `WP_Theme::get_pattern_cache` and `WP_Theme::set_pattern_cache`, have been
 made private.

 Relevant unit tests updated.

 Props afercia, flixos90, mukesh27, joemcgill.
 Merges [56978] to the 6.4 branch.
 Fixes #59633. See #59591, #59490.
