Subject: [PATCH] FinalizeTx after engine.Initialize (#5783)

AuRa storage changes made by `onEpochBegin` should be finalized.
Otherwise, `SSTORE` cost might be incorrect in block transactions when
[EIP-2200](https://eips.ethereum.org/EIPS/eip-2200) is active.
https://gnosisscan.io/tx/0xa6d45d903c977ad237165737ebc4e34fb7756675719d112a199af858bb1275e0
is an example of a transaction on Gnosis Chain whose gas used was
previously calculated incorrectly.
