hotpath: add measure to try_compress_and_encrypt and get_msg_dst_peer_ipv4

Browse Source 
Splits the 1.04us gap between send_msg_by_ip and send_msg_internal:

  try_compress_and_encrypt:     386ns (37%)  ← AES-GCM encrypt + zstd compress
  get_msg_dst_peer_ipv4:        161ns (15%)  ← IP→peer_id route lookup
  run_nic_packet_process_pipeline: 121ns (12%) ← ACL check
  other (fill_hdr + counters):  ~440ns (36%)

The 386ns encrypt is the largest optimization opportunity in this gap:
ring tunnel is in-process, so application-layer encryption may be skippable.
