Pascal Birchler 7c11d1ebf5 I18N: Actually add all the files for [58061], not just the test fixtures.
Improve support for using only PHP translation files.

This builds on top of the PHP translation file support added in WordPress 6.5, improving the behavior for projects using solely `.l10n.php` translation files and no `.mo.` and `.po` files.

Updates `wp_get_installed_translations()`, which is used when updating language packs and when uninstalling plugins/themes (to remove the translations again), to look for PHP translation files and read metadata from them. Additionally, the file lookup is now cached thanks to using `WP_Textdomain_Registry`.

Updates `Language_Pack_Upgrader::check_package()` to allow language packs that only contain PHP translation files. While WordPress.org continues to serve `.mo` and `.po` files, third-party services might want to only use the PHP file format.

See #60554.
