cameraserver: Allow CameraManager to specify rotation override for clients

CameraManager can specify a rotation override value 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 mode decided by the
WindowManager clients may want rotated sensor feeds.
