[glib] Visual Studio builds: Add script to generate utility scripts

    Visual Studio builds: Add script to generate utility scripts
    
    This will allow the utility scripts glib-mkenums and gdbus-codegen be
    generated with the proper info in them, as build systems such as Meson
    might look for shebang lines to determine the commands that need to be
    called to invoke the scripts (which is necessary for calling these
    scripts on standard Windows cmd.exe)
