AOD: Prolong AOD2 after interaction, turn off AOD when prox covered

Turns off AOD 1 and 2 when the proximity sensor is covered.
Also extends the AOD2 duration when the screen is touched or
the lift gesture is triggered.

Also fixes some issues with the fingerprint unlock transition
from AOD where the doze state for the NotificationPanelView
was cleared too early.

Also hides the wallpaper while we're dozing.
