Greatly improved Nintendo Joy-Con support using the HIDAPI driver
* 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
