ANativeWindow_setBuffersTransform: Allow forwarding INVERSE_DISPLAY
For OpenGL based camera viewfinder implementations, we want to let them
read the Transform bit off the original camera API provided image and
forward it to their OpenGL surface so they can achieve the same rotation
functionality.
Bug: 74400997
Test: Manual
