Sync focus stack frame and layer with focus app. 



Update focus stack frame/layer when focus app is changed to avoid
focus stack/layer isn't updated synchronously with focus app, it's
due to performLayoutAndPlaceSurfacesLocked() is not necessarily
called on focus app change; it will cause sending mismatching
TAP_OUTSIDE_STACK message if there is effectual incoming pointer
event, hence may also result in focus stack is changed again,
therefore erroneous focus app is set by ActivityManager at final.
