    Visual Studio: "Add" Visual Studio 2019 project files
    
    Use the scripts that we have to copy the 2010 projects and updating
    the various items in the project files to make them Visual Studio
    2019-compatible upon 'make dist'.
    
    Also ensure that the introspection NMake Makefiles can properly detect
    that we are building with Visual Studio 2019.
