Implement Controller to maintain consistency in Auto rotate settings for foldables

Implement DeviceStateAutoRotateSettingController, which is responsible for:
- Takes requests to update DEVICE_STATE_AUTO_ROTATE and ACCELEROMETER_ROTATION settings, and writes into persisted settings synchronously if the request is valid.
- Handles conflicts between incoming requests and changes, and keeps the values consistent.
- Maintains in-memory copy of the values of settings and device state.
- When it requests DEVICE_STATE_AUTO_ROTATE setting value from DeviceStateAutoRotateSettingManager, and it receives null, this class will update the persisted setting to the default value.

Follow-up CL: Handle device state being missing until we receive first device state update
