camera2 impl: Allow connecting clients to specify rotation override

CameraManager can specify a rotation override value (obtained through
other framework components in certain scenarios) which can help clients get rotated feeds
from the camera even in cases where the sensor isn't overriden to be portrait -
for example: it could already be a portrait sensor and in some device mode
decided by the WindowManager clients may want rotated sensor feeds.
