DeskClock: Replace proprietary PowerOnAlert functionality

* We don't ship PowerOnAlert app thus power off alarm handling is broken
* Try to mimic what the qcom app does. Since there is no way to continue
  boot properly after power off alarm, device will:
  - Power off when alarm is snoozed or missed
  - Reboot when alarm is dismissed
