645a8653c895e4fc7717e9e5ac045612b5deaa60 rpc: remove deprecated getaddressinfo `label` field (Jon Atack)

Pull request description:

  These were deprecated in #17578 and #17585, with expected 0.21 removal notified in the 0.20 release notes.
  ```
  - The `getaddressinfo` RPC has had its `label` field deprecated
    (re-enable for this release using the configuration parameter
    `-deprecatedrpc=label`).  The `labels` field is altered from returning
    JSON objects to returning a JSON array of label names (re-enable
    previous behavior for this release using the configuration parameter
    `-deprecatedrpc=labelspurpose`).  Backwards compatibility using the
    deprecated configuration parameters is expected to be dropped in the
    0.21 release.  (#17585, #17578)
  ```
