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

the SDL 2.24.0 stable release.
* Added SDL_bsearch() and SDL_utf8strnlen() to the stdlib routines
* Added SDL_size_mul_overflow() and SDL_size_add_overflow() for better size overflow protection
* Added support for mini-gamepad mode for Nintendo Joy-Con controllers using the HIDAPI driver
* Added the hint SDL_HINT_JOYSTICK_HIDAPI_SWITCH_COMBINE_JOY_CONS to control whether Joy-Con controllers are automatically merged into a unified gamepad when using the HIDAPI driver. This hint defaults on.
* Removed the hint SDL_HINT_JOYSTICK_HIDAPI_JOY_CONS with the new Joy-Con functionality
* Added functions to get the platform dependent name for a joystick or game controller:
* SDL_JoystickPathForIndex()
* SDL_JoystickPath()
