Unbundle the DeskClock.

- Copy some framework resources into the app.
- Add a new layout to SetAlarm to avoid using an internal id to obtain the
  content view.
- Use a string literal to identify the ALARM_CHANGED intent. This is not ideal
  but is better than exposing the actual intent string for now.
