clutter/stage: Avoid queueing stage updates when they're already queued

Browse Source 
We're using clutter_stage_schedule_update() now from ClutterActor to kick
off the stage updating machinery when a redraw needs to happen.

This introduced a bunch of unnecessary calls to
clutter_stage_schedule_update() and thus
clutter_stage_view_schedule_update() when multiple actors request redraws
during the same stage update cycle, which is a very common case.

Cut off all those unnecessary calls by bailing out in
clutter_stage_schedule_update() when updates are already queued.
