When we e.g. try to post an direct client buffer scanout update, it might arbitrarily fail; when this happen we still will want to post the rest of the update when we try again after having composited the primary plane. To do this, add a way to preserve the metadata of an update if it failed, only dropping the failed plane assignments. This involves unlocking a previously locked MetaKmsUpdate, so that e.g. a new primary plane can be assigned. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1488>
