Auto merge of #114089 - Urgau:allow-with-implied-by, r=petrochenkov
Add an allow attribute suggestion along with the implied by suggestion

This PR adds an `#[allow(...)]` attribute hep suggestion along with the implied by suggestion:
```diff
  note: `-W dead-code` implied by `-W unused`
+ help: to override `-W unused` add `#[allow(dead_code)]`
```

This PR also adds the `OnceHelp` lint level (similar to `OnceNote`) to only put the help message one time, like the implied note.
