[SDL3] Adding input and FFB support for Logitech G29(PS3) on hidapi (#11598)

Browse Source 
These changes enable the Logitech G29 wheel to run on hidapi with both SDL_Joystick and SDL_Haptic interfaces.

While it is already possible to use the wheel on Linux in WINE + SDL2 thanks to the in-tree evdev driver as well as new-lg4ff, these set of changes allow the G29 to be used with WINE under MacOS and FreeBSD

These wheels should also be supported, but I can only test them from G29's compat modes: G27, G25, DFGT, DFP, DFEX

Haptic and led support are ported from https://github.com/berarma/new-lg4ff
