[gtk/gtk-2-24] Visual Studio builds: "Add" Visual Studio 2019 projects

commit a63b70f1dc3fbd0a2e3dfad9883a1d59ce9eb310

    Visual Studio builds: "Add" Visual Studio 2019 projects
    
    Copy and update the relevant fields from the Visual Studio 2010 projects
    so that we can have project files that work out-of-the-box for Visual
    Studio 2019, as we did for Visual Studio 2012 through 2017.
    
    Also update the NMake Makefiles for building the introspection files
    so that we properly detect that we are building with Visual Studio 2019.
