7. p2p: Assume v2transport for addresses from seeds

   By now, the vast majority of nodes in the network supports BIP324.
   Even if the optimistic guess would turn out to be wrong for a given
   node, we would just reconnect with v1.
   This is better than making v1 connections with peers when both nodes support v2.

   Checked BIP 323 #34779 backports clean here. Could you add it?

10. versionbits: Limit live activation params and activation warnings per BIP323

    Test bits are conserved. This only has an effect on the warnings.

    Pushed it up here as well.

16. fuzz: Remove unused `DeserializeFromFuzzingInput` params overload

    This overload has been unused since it was added in fac81affb527132945773a5315bd27fec61ec52f.

17. fuzz, refactor: Remove `Serialize` overload

    Serialization parameters should be embedded into the object being
    serialized rather than passed as a separate argument. This works here
    because only serialization is performed and no new object needs to be
    constructed.
