Add DualShock sixaxis support

[allenftc]

The DualShock 4 controllers have a six axis imu inside. This could be useful for teams just as another control method. There is more info here https://www.psdevwiki.com/ps4/DS4-USB.

I believe that a rather significant issue here is the lack of sensor fusion on the controller for integrating the rate data.
Simply sending raw rotation rate data is probably not very useful.

I believe this issue should be reopened as the issue is not solved.
It looks like sensor fusion to integrate the rate data is done in Cemu through the Mahony system
