Disable B&R for foldables of ACCELEROMETER_ROTATION

Foldables has DEVICE_STATE_ROTATION_LOCK which stores auto-rotate setting for valid device states.
ACCELEROMETER_ROTATION setting could be different based on what device state device is in.
Eg: If the backup occurs when the device is in UNFOLDED mode and restore when device is in folded mode, ACCELEROMETER_ROTATION setting will not be restored as we expect it to be.

This change skips restoration of ACCELEROMETER_ROTATION setting if target device is a foldable.
Later ACCELEROMETER_ROTATION will be set based on device state value and restored DEVICE_STATE_ROTATION_LOCK setting in DeviceStateAutoRotateSettingController.
