[mutter/wip/carlosg/event-cleanup: 9/18] clutter: Drop CLUTTER_DESTROY_NOTIFY event

[Marge Bot <marge-bot src gnome org>]

commit 96e320ba5a2f9e191d08ce4424f659384ab02fe3
Author: Carlos Garnacho <carlosg gnome org>
Date:   Mon Dec 7 18:18:00 2020 +0100

    clutter: Drop CLUTTER_DESTROY_NOTIFY event
    
    Stop propagating this as a Clutter event. DestroyNotify is only
    relevant on nested X11 sessions, so handle it specifically in place.
