RFR: 8333653: Remove MallocHeader::get_stack [v2]

> A small and trivial enhancement, I think. Today, MallocHeader knows about the `MallocSiteTable` and vice versa. That seems a bit strange to me, as it is just a data carrier. Just have only MallocSiteTable be aware of MallocHeader by deleting a method from MallocHeader.
