chore(l1,l2): made so that the P2P logging functions say the correct file

[fedacking]

Motivation

The logs in P2P use 4 utility function to log what the peer did. (log_peer_debug, log_peer_error, log_peer_trace, log_peer_warn) These functions obscure which file triggered the log in the tracing macros. Changing those functions to macros, changes this behaviour to show the proper file. Example:
2025-10-20T21:27:08.447426Z ERROR ethrex_p2p::rlpx::utils: reth/[0xddd9…df1e(194.233.75.31:30303)]: Broken pipe with peer, disconnected
2025-10-20T21:34:24.178984Z ERROR ethrex_p2p::rlpx::connection::server: reth/[0x6101…3c5f(54.87.135.143:30303)]: Broken pipe with peer, disconnected

Description

• Changes log_peer_* functions with log_peer_*! macros, doing the same functionality.
• Step towards improving logging in L1: Improve logs and downgrade unimportant logs #4950

Did you try using #[track_caller]? I understand it's meant for something similar, but for panics. Maybe it works for this as well?

It doesn't seem to work on my testing with info!(). I think from the discussion it works with panic by making it a special case.
