libcamera: camera_sensor: Apply flips at setFormat()

Augment the CameraSensor::setFormat() function to configure horizontal
and vertical flips before applying the image format on the sensor.

Applying flips before format is crucial as they might change the Bayer
pattern ordering.

To allow users of the CameraSensor class to specify a Transform,
add to the V4L2SubdeviceFormat class a 'transform' member, by
default initialized to Transform::Identity.

Moving the handling of H/V flips to the CameraSensor class allows to
remove quite some boilerplate code from the IPU3 and RaspberryPi
pipeline handlers.

No functional changes intended.
