DO NOT MERGE ActivityView be gone!
This hidden functionality is no longer support/needed since we now have multi-window/display. A new view group class will be added later that uses multi-window to support remaining functionality of this class. Test: go/wm-smoke Change-Id: Ie2fa2de92841d33199da9988741905060dd1ddf4
