AOD: Fix wakeup transition jank

No longer do the upwards animation from AOD1, because there is a fade in instead now.

Also, because the DozeService gets finished when waking up, we were disallowing
animations again. Instead, we now ignore disallowing animations while waking up.

Also don't cancel the NotificationPanelView wakeup animation when another identical
request comes in.

Also adds tracing for various SystemUI states.

Bug: 63531607
Test: Wake up from AOD1. Ensure there is no jank or flicker
