This greatly simplifies the Rover quiktune so that it only tunes the Steering (aka Turn rate) and Speed controller feed-forward values. It then simply sets the corresponding P and I values to configurable ratios of the feed-forward.
While the rover tune received initial positive feedback, over time it became clear that the gains it produced were always too high and to get them into a reasonable range we had to set the backoff margin to ridiculously high values like 90% at which point it became very questionable as to whether the raise-gains-until-it-oscillates method is appropriate for rovers and boats.
This has been successfully tested in SITL and on a real vehicle.
This resolves issue #24729
