This helps consumers avoid having to do ugly casts
as was previously done in `SDL_quit.cs`.
It's very important that the underlying type doesn't change
as that might break ABI compat.
The bindings don't yet compile. There are errors in SDL_pixels.g.cs, SDL_stdinc.g.cs and SDL_thread.g.cs,
a bunch of warnings about "Function like macro definition records are not supported",
and a few "Info: Potential missing remapping".
