libcamera: camera_sensor: Verify flips support
During the camera sensor driver validation, verify if the sensor supports horizontal and vertical flips and store a flag as CameraSensor::supportFlips_ class member. The flag will be later inspected when applying flips. Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com>
