Tapping clock on QS launches clock app

This change mimics the behavior in the alarm tile. Tapping on the clock
either:

- Launches the alarms tab of the Clock app using the ACTION_SHOW_ALARMS
  intent. OR
- Launches the intent of the last alarm that was sent to us via
  NextAlarmController

Test: manual
Test: ShadeHeaderControllerTest
