Message:

I18N: Cache list of language file paths in WP_Textdomain_Registry.

Loading a list of language file paths using glob() can be expensive if involving thousands of files.

Expands scope of WP_Textdomain_Registry to cache list of language file paths in object cache and provides a way to invalidate that cache upon translation updates. Plugins can clear the cache using calls such as wp_cache_delete( 'cached_mo_files_' . md5( $path ), 'translations' );

Props mreishus, swissspidy
Fixes #58919
