clutter/stage: Subclass ClutterActor

Browse Source 
ClutterStage is the one and only subclass of ClutterGroup, but
it overrides basically everything specific to ClutterGroup to
mimic a ClutterActor. What a waste!

Subclass ClutterActor directly and remove all the now useless
vfunc overrides from ClutterStage. Adapt CallyStage to subclass
CallyActor as well.
