Native NSO GameCube controller support (and the other Switch 2 controllers)#927

Right now, The Switch 2 controllers (Procon 2, NSO GCN, and JoyCon 2) are all supported over USB in both Steam Input and in SDL, but the game still lacks native support for them. The reliance on Steam Input to get these controllers working in-game has caused a lot of problems for people, with layout differences, latency problems and issues with stick calibration, but there’s no alternative to using them without Steam Input.

All those are good enough reasons but personally, I just think it’d be real convenient to have background input while I’m playing with my NSO GCN…

I think reworking the GCC support to be compatible with Steam Input’s own support would be good.
