Query: Avoid unnecessary database query when deleting a font family.

Querying only the font face IDs is sufficient when deleting a font family. There is no need to warm the caches with the full objects, since `wp_delete_post()` will always make a direct database query to get the object anyway.

Props dilipbheda.
Fixes #63014.
