Trigger doze detection using WakefulnessLifecycle

Previously, doze detection used StatusBarStateController, which only
provides a signal at the end of the doze transition. This resulted in
the handles only animating away once the screen was already off. Using
the WakefulnessLifecycle allows for a callback when the transition
begins instead.
