This PR drops support for eth/64. Unfortunately, there's not much more we can do now to clean up our codebase until we also start dropping eth/65. That said, after Berlin it's probably safe to still serve but not sync from below eth/66, which would simplify certain things.

The PR also enabled eth/66 tests at various locations that didn't have them run and fixes them to complete successfully.

IIRC, there's also some logic within the tx broadcast loop, to check if a peer is 65+ or less, to fall back to broadcast instead of announce. We can remove that too

Got ACK from Besu, Turbo-geth and Nethermind that they speak 65. OE has seen my question, but not given a clear answer yet.
