Extract common types from sync

What type of PR is this?

Other/Refactoring

What does this PR do? Why is it needed?

• Extracted from Peer status peer scorer #7480
• Peer scorers need access to common sync errors and possible goodbye messages (codes). Particularly, status peer scorer (implemented in Peer status peer scorer #7480, that scorer decides whether peer is good/bad based on validation error).
• When it comes to goodbye codes - then they are used as an extra elaboration on why peer is considered bad:

// Disconnect from peers that are considered bad by any of the registered scorers.
if s.p2p.Peers().Scorers().IsBadPeer(id) {
	goodbyeCode := p2ptypes.ErrToGoodbyeCode(s.p2p.Peers().Scorers().ValidationError(id))
	if err := s.sendGoodByeAndDisconnect(s.ctx, goodbyeCode, id); err != nil {
		log.Debugf("Error when disconnecting with bad peer: %v", err)
	}
	return
}

• This PR moves error messages and goodbye codes into p2p/types sub-package (we cannot move to p2p as it will create circular dependency p2p/peers/scorers -> p2p -> p2p/peers/scorers).
