    MSVC builds: Adapt to Pythonfied glib-mkenums
    
    glib-mkenums has been re-written in Python in the later GLib since 2.54,
    so we need to adapt to it.
    
    The issue is that the standard Windows cmd.exe (where the Visual Studio
    projects make use of) does not support shebang lines, and we still
    support GLib versions that use the PERL glib-mkenums, we need to first
    try to run that script with Python (which we already use during the
    build) and see whether that was successful by seeing whether the
    generated file is not empty (as calling the PERL glib-mkenums would
    cause an error and results in the generated file being 0 in size).
    
    If calling glib-mkenums with Python failed, call that script with PERL,
    as we did before.
