clutter/stage-view: Give a stage view a refresh rate
Currently unused, but it's intention is to use as a initial refresh rate for a with the stage view associated frame clock. It defaults to 60 Hz if nothing sets it, but the native backend sets it to the associated CRTCs current mode's refresh rate. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
