Add cemuhook motion control support

[greasysock]

Cemuhook recently added a backend to cemu for hosting a udp server and having motion data and controller data sent to cemu. I think this would be the perfect program to implement this feature since this is a Nintendo emulator and these controllers are designed for those games.

Now the vjoy controller cannot be used in cemu.
