Warn about priority change in implicit search only if one of the participating candidates appears in the final result.

It could be that we have an priority change between two ranked candidates that both are superseded by the result of the implicit search. In this case, no warning needs to be reported.

This PR is #20480 with different code for the last commit. I tried to avoid entangling the priority handling too much in the returns types and spent a side effect instead. I believe it's more efficient that way, since priority warnings are very rare.

Fixes #20484
