`BKE_main_collections_parent_relations_rebuild`, `BKE_collection_parent_relations_rebuild` anf their internal dependencies had two issues fixed by this commit: * Main one was that a same collection could be processed several times, sometimes even in an infinite loop (in some rare corner cases), by `collection_parents_rebuild_recursive`. * More exotic, code here would not ensure that the collections it was processing were actually in Main (or a master one from a scene in Main), which became an issue with some advanced ID management processes involving partially out-of-main remapping, like liboverride resync.
