[core#19724 3/9][refactor] Restructure logic to check for addr relay.

Summary:
We previously identified if we relay addresses to the connection by checking
for the existence of the m_addr_known data structure. With this commit, we
answer this question based on the connection type.

IsAddrRelayPeer() checked for the existence of the m_addr_known

This is a backport of core#19724 [3/9]
