efl_object: add call for getting invalidating

Summary:
there is now invalidated & invalidating.

invalidated returns true when all children are invalidated, and the
object is / was requested to be invalidated.

invalidating return true when the object is called to be invalidated but
not all children are invalidated yet. However, the object is garanteed
to be invalidated in near future.
