 I18N: Change how `WP_Textdomain_Registry` caches translation information.

 `WP_Textdomain_Registry` was introduced in [53874] and later adjusted in
 [54682] to store text domains and their language directory paths,
 addressing issues with just-in-time loading of textdomains when using
 locale switching and `load_*_textdomain()` functions.

 This change improves how the class stores information about all existing
 MO files on the site, addressing an issue where translations are not
 loaded after calling `switch_to_locale()`.

 Props johnbillion, ocean90, SergeyBiryukov.
 Fixes #57116.
