[gimp/wip/Jehan/layers-dockable-refresh: 126/126] app: more removal of item link related code.

[Jehan <jehanp src gnome org>]

commit c0ea7b36695c968ba4e07136f1f1540324ab4c0f
Author: Jehan <jehan girinstud io>
Date:   Thu Dec 16 00:08:15 2021 +0100

    app: more removal of item link related code.
    
    - removing the GIMP_ITEM_SET_LINKED enum value.
    - removing gimp_image_item_list_linked(). Now we should directly use
      gimp_image_item_list_filter() instead.
    - "preview-linked" option for transform tools is no more.
