Removed the mapping of objects to their save count, in favor of putting the save count into a new FObjectRecords struct, and mapping objects to that instead. This allows the records for an object to be found via the map, and avoids the remaining look-up overhead of searching the records array during object snapshotting.
The object records map keys against the FPersistentObjectRef rather than the raw-UObject, so that the record for sub-objects can be found correctly even if the sub-object is re-created.

FPersistentObjectRef would perform a StaticFindObject for each sub-object in its object chain, for each request to resolve the object pointer. This could be quite costly when finding the record for a large transaction (eg, when moving thousands of objects).
This change stores a cache of the resolved object chain, and will use this cache if every object in the chain still passes its validation check. In order to do this, the guts of FPersistentObjectRef have been made private, and the -> operator was also removed as it could promote writing code that would repeatedly resolve the object pointer.
