android: CameraDevice: Validate crop_rotate_scale_degrees in configuration

Browse source 
libcamera doesn't handle |crop_rotate_scale_degrees| in
camera3_stream at all. This adds the validation of the requested
|crop_rotate_scale_degrees| in configuration, but still not
handle the specified values.
