clutter/stage: Store a list of all active gestures on the whole stage

Browse Source 
With the next commit, we'll need a list of all gestures that currently are
active globally. Since actors and actions (and therefore also gestures) in
Clutter are bound to a stage, it makes sense for this list to exist on the
ClutterStage level.

The list itself is a simple GPtrArray (to allow for quick searches) that
doesn't reference the gestures and is not manipulated by the stage itself.
All manipulation of the array is left to ClutterGestures.
