* FW attitude control scaling fixes and cleanup
This commit aligns the scaling better with the derivations in
https://dev.px4.io/master/en/flight_stack/controller_diagrams.html#airspeed-scaling
Integrator terms now scale with IAS^2 (all three axes)
To match the roll and pitch controllers:
- Yaw integrator scale is now applied during accumulation, not to
integral value (so now FW_YR_IMAX is respected more intuitively)
- Yaw FF term now scale with IAS instead of IAS^2
Also made a number of small changes to make the three files
(roll, pitch, yaw) 3-way diffable to be clearer about what the
differences among them are.
* Remove unused yaw coordination method
- "Coordination method" open vs. closed code removed, since closed
is never used and not actually implemented.
- No change to behavior
* Remove PX4_WARN messages

- ecl/attitude_fw was never maintained as a standalone library
- moving ecl/attitude_fw library into the fw_att_control module to ease further development
