Arrow Glacier fork Add the new [Arrow Glacier fork](https://eips.ethereum.org/EIPS/eip-4345). Only the difficulty calculation is changed, but as a new fork it still affects a number of places in the code. To the best of my knowledge the change is only scheduled on Mainnet. In addition: - The fork date comments in `chain_config.nim` have been checked against the real networks, set consistently in UTC instead of random timezones, and made neater. Maybe we'll keep these when transferring config to a file someday. - It's added to forkid hash tests (EIP-2124/EIP-2364), of course. Signed-off-by: Jamie Lokier <jamie@shareable.org>
