Defer updating dim layers if layout is deferred
When a translucent activity is on top of launcher and the activity
is animated away, we update the layers too early in case the
activity window is dimming. After starting the launcher, launcher
is on top of activity already in the hierarchy, but we haven't
started the transtion yet which would prevent the launcher to be
visible on top of activity by the anim layer adjustment.
To fix this, we prevent updating the layers if layout is currently
deferred.
Ideally we would do the whole activityStart in one surface
transaction but that's way too risky at this point.
Test: Open translucent dimming activity over launcher, press home,
ensure no flickering.
Test: go/wm-smoke
