Works around a flaw in the upgrade logic of the system contracts. Since they are updated directly, without first being self-destructed and then re-created, the usual incarnation logic does not get activated, and all historical records of the code of these contracts are retrieved as the most recent version. This problem will not exist in erigon3, but until then, a workaround will be used to access code of such contracts through a special structure, `SystemContractCodeLookup` Fixes https://github.com/ledgerwatch/erigon/issues/5865 Co-authored-by: Alexey Sharp <alexeysharp@Alexeys-iMac.local>
