Checking whether relations already existed was a bottleneck when building collection -> object hierarchy relations. The duplicate checking would be unnecessary since an object can only be in a collection once, but this function to build relations can be called multiple times for the same collection. To avoid the need to check for duplicates, only run the relation creation once for each collection. The `BuilderMap` gives a simple way to do that. Note that because a collection might be built separately as a non-layer collection, there may still be duplicate hierarchy relations. Building a Depsgraph for 60k simple objects became 1.86x faster, from 2.39 to 1.29 seconds. Pull Request: https://projects.blender.org/blender/blender/pulls/137737
