Add support for device state based auto-rotation preferences in Settings.

- Creates new preferences that are shown when device-state rotation
  is supported.
- Hides standard preferences when device-state rotation is supported.
- Controllers/Preferences for individual folded/unfolded rotation
  settings are created and added programatically based on the settable
  device states available.
