Request compassmot for the plane firmware

[leondwyer]

First raised in 2015 and closed with reason "compassmot will soon be replaced by an in-flight auto-learning scheme for both platforms."
#2204

Feature request

I am receiving a lot of compass errors due to the small platform that I'm building on.
I am unable to move hi-current wires further from the compasses nor is shielding proving to be effective.
Auto learns compasses is not resolving the issue.

Describe the solution you'd like
Please add compass mot calibration to the plane firmware

Describe alternatives you've considered
Relaying out wires, wire shielding, inflight calibration, turning off onboard compasses, and the dreaded flying on 1 compass

Platform

#17801 adds the ability to calibrate onboard, but it not yet merged.
