rABCa6e41eea5772: [avalanche] Don't rely on the service bit for sending the avalanche message

Summary

This leverage the avahello message to determine if a peer has avalanche enabled rather than relying on the service bit or the ability to ignore the unsupported messages. This will let poll only nodes (that don't set the service bit) participate in the address and compact proof messaging.

Sending the getavaaddr and getavaproofs are now sent upon reception of the avahello message instead of the version message.

The tests are updated in a way that makes them closer to the actual real use case: the nodes are non longer connected via RPC but use the regular peer discovery mechanism instead.

Depends on D11723.

4911–4941	The fact the message name made no sense was already a hint, but the fact all of this needs to be moved here is another. When you need to do a handshake before you do the handshake, you know you have one too many handshake.

This revision now requires changes to proceed.Jul 5 2022, 12:58

313 ↗	(On Diff #34296)	Is this necessary?
test/functional/test_framework/avatools.py
287 ↗	(On Diff #34296)	It seems like this should be the default interface to use in tests, so naming it AvaP2PInterface is more appropriate. There are not very many direct usages of the base interface, so maybe name the base something like NoHandshakeAvaP2PInterface to make it clear.
