Add a flag to specify rotate-and-crop rotation degrees.

For landscape foldables, and portrait tablets whose main
landscape orientation is 270 degrees, rotate-and-crop is 90.
However, most portrait devices work best in landscape rotation 90,
therefore it is important to be able to specify rotate-and-crop=270.

Rotation data will be sent from Window Manager (system process), and accessed in the Camera Framework (mainly CameraManager in the app process), as the display rotation might be sandboxed for the app process as part of the camera compat treatment, and Camera Manager might not be able to access the real display rotation.
