clutter/actor: Invalidate stage-views on transformation changes

Browse Source 
Since we now have the neccessary infrastructure to get notified about
changes to the absolute transformation matrix, we can also invalidate
the stage-views list on updates to this matrix.

So rename absolute_allocation_changed() to absolute_geometry_changed()
to make it clear this function is not only about allocations, and call
that function recursively for all children on changes to the
transformation matrix, too.
