clutter: Move redraw clip management to views
The stage window handled the redraw clip in a global manner; this would interfere if we want to paint views individually as it'd mean intersecting views (i.e. mirrored monitors) would loose the redraw clip once the first view was painted. It also is awkward to have a global state for something that is built up before redrawing, and only really valid during paint, due to buffer damage history. This commits removes all redraw clip management from the stage window, moving it all into the stage views. When a redraw clip is added to the stage, every affected view will get the same redraw clip added to it, and eventually when painted, the stage window (ClutterStageCogl) will retrieve the redraw clip for each view as it repaints them. https://gitlab.gnome.org/GNOME/mutter/merge_requests/1042
