    Add back ACCELEROMETER_ROTATION_ANGLES and update references

    This needed to move back into fw/b, because it needs to be
    accessed from inside the RotationPolicy. Previously
    (when this constant and Setting were located in lineage-sdk),
    the settings for the display rotation had no effect, because we
    couldn't query the correct set of settings.

    Rotation related corrections

    - There are some conditions deleted while placing rotation angles code, I added them.

    - Rotation lock was screwed up since CM 12. Fixed it by fetching allowed rotations from CM's
    allowed rotations setting.

    - Also, a CAF commit had killed rotation lock ability.

    [port to 15.1]:
     - ACCELEROMETER_ROTATION_ANGLES moved to LineageSDK
     - Slight change of the WindowManager API

    [port to 16.0]:
     - adjust context
     - ACCELEROMETER_ROTATION_ANGLES moved to Settings
     - Use the configstore API
