Umang Jain a18c9f0490 libcamera: camera_sensor: Transform CameraSensor::sizes()
In CameraSensor, the mbusCodes() and sizes() accessor functions
retrieves all the supported media bus codes and the supported sizes
respectively. However, this is quite limiting since the caller
probably isn't in a position to match which range of sizes are
supported for a particular mbusCode.

Hence, the caller is most likely interested to know about the sizes
supported for a particular media bus code. This patch transforms the
existing CameraSensor::sizes() to CameraSensor::sizes(mbuscode) to
achieve that goal.

The patch also transforms existing CIO2Device::sizes() in IPU3 pipeline
handler to CIO2Device::sizes(PixelFormat) on a similar principle. The
function is then plumbed to CameraSensor::sizes(mbusCode) to enumerate
the per-format sizes as required in
PipelineHandlerIPU3::generateConfiguration().
