[gnome-games/wip/exalm/gtk4: 9/48] message-dialog: Don't subclass GtkMessageDialog

[Alexander Mikhaylenko <alexm src gnome org>]

    message-dialog: Don't subclass GtkMessageDialog
    
    We cannot do this in GTK4. Because of that, reimplement this type of
    dialog and only subclass GtkDialog.
    
    This introduces a deprecation that will be fixed in later commits.
