[Build] Fix building on Windows

This merge request implements support for building on Windows.

The requirements are:

• Visual Studio Build Tools 2022 with the following entries installed:
  • MSVC v143
  • Windows 11 SDK
• llvm and ninja (optional)

Default (MSVC)

By default, CMake will use the Visual Studio 17 2022 generator and build with MSVC and MSBuild. The executable will be placed inside a Debug/Release folder inside the build directory.

Ninja (LLVM/Clang)

When ninja is installed, sbs will detect it and set it as the generator. The only toolchain that has been tested to work is the llvm toolchain, which can be installed via winget. The way LLVM works on Windows is that it uses the clang compiler to produce the object files, then uses MSVC to link with Windows libraries.

I didn't even try to get MinGW to work. MinGW is a huge pile of shit and it needs to die.
