feat(l1): add p2p context

[Arkenan]

Motivation

There are many shared attributes in all p2p tasks:

• Local node
• Signer
• TCP and UDP addresses
• RLPX message Broadcaster.
• Kademlia table.

This makes the number of arguments big in all calls, and sometimes even repeated (e.g. addresses + node). Additionally, Adding a new argument related to all, like the broadcaster, also requires adding it everywhere.

Changes

This PR adds a Context struct with all the mentioned common fields and uses it instead of the individual fields. There's also 2 new helpers in the Node struct, for udp and tcp addresses.
