Use shade motion events from NotificationPanelViewController as an early signal for shade expansion.

Improves the early signal timing in the following CUJs:
 1. Swipe down from top of screen (from status bar)
 2. Long press status bar (previous signal was not getting triggered for this)

CUJs that still have the same timing:
 1. Swipe down while on launcher from the center of the screen
 2. Swipe down from a HUN

Note: all of these are non-lockscreen CUJs. early wakeup flag is always true while on the lockscreen.
