 A ticket to track the syncing of Gutenberg PR:
 https://github.com/WordPress/gutenberg/pull/66155

 === What
 Implement "pretty basic caching" for resolved theme URIs in
 `WP_Theme_JSON_Resolver::get_resolved_theme_uris`.


 The intention to improve performance, even if slightly.

 `WP_Theme_JSON_Resolver::get_resolved_theme_uris`, and
 `WP_Theme_JSON_Resolver::resolve_theme_file_uris` which calls it, is fired
 multiple times in a single session to:

 1. Generate styles
 2. Deliver resolved URIs in a global styles controller response.


 Results will become more pronounced as other relative paths are
 introduced, e.g., [https://github.com/WordPress/gutenberg/pull/65019
 fonts], and more blocks support background images.

 Cached data is not be stored persistently across page loads.
