Greatly improved Nintendo Joy-Con support using the HIDAPI driver

Browse Source 
* Added support for mini-gamepad mode for Joy-Con controllers, matching the mapping for hid-nintendo on Linux and iOS 16
* Added the ability to merge left and right Joy-Con controllers into a single Pro-style controller
* Added the hint SDL_HINT_JOYSTICK_HIDAPI_SWITCH_COMBINE_JOY_CONS to control this merging functionality
* Removed the hint SDL_HINT_JOYSTICK_HIDAPI_JOY_CONS
