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.
This is done by adding a `Unsafe_` prefix to `(const) char *` (C# `byte*`) functions.
I am using `string?` instead of `ReadOnlyMemory<byte>?` because the returned pointer can
get invalidated and cause memory-safety issues.
The returned pointer is automatically freed if the return type is `char *`.
I've checked that the documentation for all functions (except in SDL_stdinc.h)
requires calling `SDL_free()` on the pointer.
All of these get "Function like macro definition records are not supported: [...] Generated bindings may be incomplete."
warnings when running ClangSharp.
Produces a lot of noise about unused remappings (as we're processing a header at a time).
All remappings (except `SDL_JoystickGUID`) have been added.
`SDL_JoystickGUID` is a remapping of a struct, so it's harded to do programatically.
Probably needs similar undefines on Linux and macOS.
Notice that the signatures of `SDL_CreateThread` and `SDL_CreateThreadWithStackSize`
have changed.
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".
