p2p: Split network logging into two categories #24247 #24273

This PR is to resolve issue 20576. It focuses on introducing different levels of net logging. As a starting point, as mentioned in the issue #20576 , it creates separate lower-frequency, important peer-level events (netpeers) from very high-frequency message-level passing (netmessages).

Thanks! But instead of splitting up net specifically, I think a better option is to add logging verbosity in general. Closing in favor of #24464.
