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.

    LGTM. Differences in 35679 are due to adapting to the 30.0 codebase

    I verified that all backport commits apply cleanly, except:

    • small documentation fixups in a80c96280f9a documentation to reflect that this is on branch 30.x
    • merge conflict in 945aa9866ecc from earlier changes to DeserializeFromFuzzingInput, trivially addressed as the overload is removed

    The backports and changes all seem sensible for 30.x, and the release notes look correct too.
