clutter/actor: Add semi-private API to check for transitions

Browse Source 
Transitions are used for animating actors when e.g. going from/to
fullscreen, and the like. We need to know such things when deciding
whether to avoid compositing a window actor, so make add API visible to
mutter that checks whether there are any transitions active.
