Include embedding activity change in transition

Browse Source 
When enter ActivityEmbedding split, we will reparent the fill parent
activity to an embedded TaskFragment of different size. Before, because
the embedded TaskFragment is also a change target, the activity will be
excluded from the change targets. Now, we also include such activity so
that we can animate the transition of it.
