idz, idac, swdc: Added separate pedals config, better XInput controls

- Configure separate pedals which are not part of the steering wheel (base)
 - It is now possible to have a different steering wheel, pedal and shifter brand all connected to 3 different USB ports
- XInput does not have a deadzone at the end of the max steering anymore and the `restrict` setting works as intended
