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
