[gnome-shell] windowManager: Use MetaWindow.has_attached_dialogs()

[Marge Bot <marge-bot src gnome org>]

    windowManager: Use MetaWindow.has_attached_dialogs()
    
    Now that MetaWindow itself exposes a method for checking for
    attached dialogs, we can use that instead of our own helper
    method.
