Message:

I18N: Support loading .l10n.php translation files on their own.

Adjusts the translation file lookup in WP_Textdomain_Registry so that just-in-time translation loading
works even if there is only a .l10n.php translation file without a corresponding .mo file.

While language packs continue to contain both file types, this makes it easier to use translations in a project
without having to deal with .mo or .po files.

Props Chrystl.
See #59656.
