libcamera: rpi: pipeline_base: Move findBestFormat to CameraData
The findBestFormat() helper operates on the list of sensor formats, which is owned by the CameraData class. Move the function to that class as well to: 1) Avoid passing the list of formats to the function 2) Remove a static helper in favour of a class function 3) Allow subclasses with access to CameraData to call the function Move to the CameraData class the scoreFormat helper as well.
