Media: Revert `wp_ajax_save_attachment_updated` hook.

This changeset removes the `wp_ajax_save_attachment_updated` hook by reverting [55106], [55111], and [55450], to give it more time for further discussions as there are still concerns about whether this hook is necessary.

Follow-up to [55106], [55111], [55450].
