Update process animating state with different reasons

Since shell transition is enabled, it is more often to invoke
setRunningRemoteAnimation for SystemUI. So there may a race
race that SystemUI has been boosted for entering AOD, but the
state is canceled by a finished transition.

So now with individual animating reasons, the transition will
only remove its corresponding reason. If other reasons still exist,
the process can keep the animating state for a higher priority.
