Instead of using the "discarded" page flip callback when the "discarding" happened during actual immediate processing, communicate the same via the KMS update feedback. The "discarded" page flip callback is instead used only for when a posted page flip is discarded. In the atomic backend, this only happens on shutdown, while in the simple backend, this also happens when a asynchronous retry sequence eventually is abandoned. This allows further improvements making KMS handling fully async. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2854>
