Do not access CNetAddr::ip directly from CService methods.

This improvement will help later when we change the type of
CNetAddr::ip (in the BIP155 implementation).

(chopped off from #19031 to ease review)

All modified code is covered by existent tests. For example: CService::GetKey().

Updated to use CNetAddr::GetAddrBytes(), see #19031 (comment) for longer explanation.

Now this PR is even simpler.

I like auto, but if this is critical code, maybe it would be prudent to use the explicit std::vector<unsigned char> type.

This should be updated to use the new AsBase<> syntax from #19503 if that PR gets merged first.

Pull request description:

  Conjunction of a large number of back ports, updates and refactorings that made with the final goal of implementing v3 Onion addresses support (BIP155 https://github.com/bitcoin/bips/blob/master/bip-0155.mediawiki) before the tor v2 addresses EOL, scheduled, by the Tor project, for (1) July 15th: v2 addr support removal from the code base, and (2) October 15th: v2 addr network disable, where **every peer in our network running under Tor will loose the connection and drop the network**.

  As BIP155 describes, this is introducing a new P2P message to gossip longer node addresses over the P2P network. This is required to support new-generation Onion addresses, I2P, and potentially other networks that have longer endpoint addresses than fit in the 128 bits of the current addr message.

  In order to achieve the end goal, had to:
  1.  Create Span class and push it up to latest Bitcoin implementation.
  2.  Update the whole serialization framework and every object using it up to latest Bitcoin implementation (3-4 years ahead of what we currently are in master).
  3.  Update the address manager implementing ASN-based bucketing of the network nodes.
  4.  Update and refactor the netAddress and address manager tests to latest Bitcoin implementation (4 years ahead of what we currently are in master).
  5.  Several util string, vector, encodings, parsing, hashing backports and more..

  Important note:
  This PR it is not meant to be merged as a standalone PR, will decouple smaller ones moving on. Adding on each sub-PR its own description isolated from this big monster.

  Second note:
  This is still a **work-in-progress**, not ready for testing yet. I'm probably missing to mention few PRs that have already adapted to our sources. Just making it public so can decouple the changes, we can start merging them and i can continue working a bit more confortable (rebase a +170 commits separate branch is not fun..).
