Wine needs to setup each thread that has an access to Windows APIs. It means that in winelib builds, we can't let standard C++ library create threads and need to use Wine for that instead. I wrote a thin wrapper around Windows thread functions so that the rest of code just has to use new dxvk::thread class instead of std::thread.
