Message:

I18N: Introduce WP_Textdomain_Registry to store text domains and their language directory paths.

Previously, when using switch_to_locale() all current loaded text domains were unloaded and added to the $l10n_unloaded global. This prevented the just-in-time loading for text domains after a switch. The just-in-time loading was also only possible if the translations were stored in WP_LANG_DIR. Both issues have been fixed.

• Adds WP_Textdomain_Registry to keep track of the language directory paths for all plugins and themes.
• Updates all load_*_textdomain() functions to store the path in WP_Textdomain_Registry.
• Adds $reloadable parameter to unload_textdomain() to define whether a text domain can be loaded just-in-time again. This is used by WP_Locale_Switcher::load_translations().
• Extends _load_textdomain_just_in_time() to also support text domains of plugins and themes with custom language directories.
• Fixes the incorrect test_plugin_translation_after_switching_locale_twice() test which should have catch this issue earlier.
• Adds a new test plugin/theme to test the loading of translations with a custom language directory.
• Deprecates the now unused and private _get_path_to_translation() and _get_path_to_translation_from_lang_dir() functions.

Props yoavf, swissspidy, dd32, ocean90.
See #26511.
Fixes #39210.
