[CameraCompat] Use device sensor rotation when app is on external display.

Different natural orienations and display rotations can cause compatibility issues. This change uses `OrientationEventListener` (rotation sensor) to keep the camera preview upright.

This change only affects apps with existing camera compat treatments (fixed orientation).
