Fills PayloadAtEnd in place on each step whose end is null and whose PayloadAtEndSourceStepID
resolves (see ResolvePayloadAtEnd), so code that reads PayloadAtEnd gets the end
payload. Other steps are left as they are. Meant for readers that load all steps of one run; accepts
entity objects or plain rows.
