[gtk/more-vs-proj-updates: 5/9] win32/generate-msvc.mak: Add rules for gtk30[-properties].pot

commit e7f67bd3924a28abe9ca2a2bcf7c7bce1e338cf8

    win32/generate-msvc.mak: Add rules for gtk30[-properties].pot
    
    This adds rules using xgettext to generate gtk30.pot and
    gtk30-properties.pot.
    
    Currently, the XGETTEXT=... must be supplied, since it will likely come
    from a MSYS2 or Cygwin installation on Windows.
    
    This will help us get closer to support building more directly from a
    GIT checkout with the Visual Studio projects
