Fix T89835: Crash after Instancing to Scene after making linked Collection local. 

Even though the ID itself remain the same after being made local, from
depsgraph point of view this is a different ID. Hence we need to tag all
of its users for COW update, as well as rebuild depsgraph relationships.

Should be also backported to LTS 2.93 (and 2.83 if possible).
