Subject: [PATCH] cmake: Add missing SDL_JOYSTICK_WGI in config step

SDL_config.h *can* define SDL_JOYSTICK_WGI. On builds with the Windows
10 SDK available, this allow implementing trigger rumbling on Xbox One
controllers. The files included in the Visual Studio Solution in
VisualC\SDL.sln *do* have this define set.

fix #4859
