Improve doze transitions
This change animates the status bar and the bottom area when exiting
doze mode from touch. We also prevent all animations when exiting
from other means, i.e. usually when the power button is pressed, so
we don't have a distracting animation there. In addition, this also
optimizes the scrim animations a bit in terms of interpolation and
duration to make the experience smoother and cleans up some logic.
