I18N: Prevent incorrect language dropdown entries when there are .l10n.php files.

Browse Source 
In [57516], the just-in-time translation loading logic was enhanced to support cases where only `.l10n.php` translation exist but no `.mo` or `.po` files. This caused a slight regression in `get_available_languages()`, which uses the list of files to populate the language dropdown list on the settings page.

To address this, the new file extension is now properly stripped off, and the resulting file list is de-duplicated. New test files are added to allow the existing tests to cover this new scenario.

See #59656.
Fixes #60553.
