Pascal Birchler 8d3e4a1eeb 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.
