windows.gaming.input: Assume that joysticks with single FFB axis are racing wheels.

The HID PID steering wheels always declare one force feedback axis,
while the joysticks always have two or more. So it is safe to
assume that joysticks with single FFB axis are racing wheels.

Fixes FH5 not having force feedback with a Simucube 2 steering
wheel, when using the hidraw backend.
