Handling DPI Awareness on Windows

[MasonAlice]

before create win32 window, tell system not to automatically scale. I copy source code from vulkan-example here:

typedef HRESULT*(__stdcall * SetProcessDpiAwarenessFunc)(PROCESS_DPI_AWARENESS);

    HMODULE shCore = LoadLibraryA("Shcore.dll");
    if (shCore)
    {
        SetProcessDpiAwarenessFunc setProcessDpiAwareness =
            (SetProcessDpiAwarenessFunc)GetProcAddress(shCore, "SetProcessDpiAwareness");

        if (setProcessDpiAwareness != nullptr)
        {
            setProcessDpiAwareness(PROCESS_PER_MONITOR_DPI_AWARE);
        }

        FreeLibrary(shCore);
    }
