[mutter] display: Add API to set wm_name / wm_keybindings

    display: Add API to set wm_name / wm_keybindings
    
    As plugins can now define their own keyboard shortcuts via
    meta_display_add_keybinding(), it makes sense for them to
    expose those shortcuts to System Settings, so add some API
    to set the properties gnome-control-center uses to pick up
    wm keybinding settings.
