Demote top app scheduling group when unlocking
SystemUI may be running the unlock animation. If both SystemUI
and the resuming top app have top-app scheduling group, there
may be CPU contention which causes animation jank.
An exceptional case is unlocking to home which may also animate,
then keep original behavior: both system ui and home will have
top-app scheduling group.
