Unload the Vulkan library previously loaded by SDL_Vulkan_LoadLibrary().
SDL keeps a counter of how many times this function has been called, so it
is safe to call this function multiple times, so long as it is paired with
an equivalent number of calls to SDL_Vulkan_LoadLibrary. The library isn't
actually unloaded until there have been an equivalent number of calls to
SDL_Vulkan_UnloadLibrary.
Once the library has actually been unloaded, if any Vulkan instances
remain, they will likely crash the program. Clean up any existing Vulkan
resources, and destroy appropriate windows, renderers and GPU devices
before calling this function.
