  [ORC] Fix transfer to unknown ResourceTrackers (#114063)

When transferring resources, the destination tracker key may not be in
the internal map, invalidating iterators and value references. The added
test creates such situation and would fail before with "Finalized
allocation was not deallocated."

For good measure, fix the same pattern in RTDyldObjectLinkingLayer
which is harder to test because it "only" results in memory managers
being deleted in the wrong order.
