mem: Add a MemBackdoor type to track memory backdoors.
These are similar to the structures TLM's DMI mechanism uses. Instead
of having an invalidation broadcast which propogates backwards up the
port hierarchy, this mechanism tracks a set of callbacks which are
triggered when a back door is invalidated to let other holders clean
up their bookkeeping.
