Apply "most-recent" delivery policy to certain broadcasts.

Applying the policy to DEVICE_IDLE_MODE_CHANGED and
LIGHT_DEVICE_IDLE_MODE_CHANGED broadcasts so that when dispatching
these broadcasts, we can discard any older broadcasts waiting
to be delivered and deliver only the most recent to the receivers.
