swarm, p2p: Prerequities for ENR replacing handshake (#19275) 

* swarm/api, swarm/network, p2p/simulations: Prerequisites for handshake remove

* swarm, p2p: Add full sim node configs for protocoltester

* swarm/network: Make stream package pass tests

* swarm/network: Extract peer and addr types out of protocol file

* p2p, swarm: Make p2p/protocols tests pass + rename types.go

* swarm/network: Deactivate ExecAdapter test until binary ENR prep

* swarm/api: Remove comments

* swarm/network: Uncomment bootnode record load
