Themes: Cache block theme patterns in a transient.

Browse Source 
This extends the benefits of persistent caching added in [56978] for block theme patterns to sites that are not using a persistent object cache. By default, these caches expire using the value of the `WP_Theme::cache_expiration` property. The transient cache TTL can be overridden using the newly introduced `wp_theme_files_cache_ttl` filter.

See #59600, #59719.
