[Help wanted] Compile raylib on macOS

Currently compiling raylib on macOS is unsupported. The closest we ever got is this commit which segmentation faulted for at least two reasons:

The buffer passed to std.fmt.bufPrint is too small for the given string
Some unknown reason, fixing it will probably make compilation work

Compiling raylib's built-in version of GLFW will most likely never work, since it requires compilation of Objective-C code, however, we can use the system version of GLFW if present. Help is much appreciated.
