Merge bitcoin/bitcoin#22501: netinfo: display addr_{processed, rate_limited, relay_enabled} and relaytxes data 
218862a01848f69d54380c780bb5eae6dfdb1416 Display peers in -netinfo that we don't relay addresses to (Jon Atack)
3834e23b251ed7b4a47bbb981faba65b97ecbba0 Display peers in -netinfo that request we not relay transactions (Jon Atack)
0a9ee3a2c787e97213a0456b0d6253c549b71e09 Simplify a few conditionals in -netinfo (Jon Atack)
5eeea8e2575a36587e70743af3bd7c2d87b8cf36 Add addr_processed and addr_rate_limited stats to -netinfo (Jon Atack)

Pull request description:

  Update CLI -netinfo to display the getpeerinfo `addr_processed`, `addr_rate_limited`, `addr_relay_enabled` and `relaytxes` data with auto-adjusting column widths.

  ```
  $ ./src/bitcoin-cli -netinfo help

    txn      Time since last novel transaction received from the peer and accepted into our mempool, in minutes
             "*" - the peer requested we not relay transactions to it (relaytxes is false)

    addrp    Total number of addresses processed, excluding those dropped due to rate limiting
             "." - we do not relay addresses to this peer (addr_relay_enabled is false)

    addrl    Total number of addresses dropped due to rate limiting
  ```
