Rollup merge of #98799 - jyn514:rustdoc-lint-help, r=GuillaumeGomez

Fix bug in `rustdoc -Whelp`

Previously, this printed the debugging options, not the lint options,
and only handled `-Whelp`, not `-A/-D/-F`.

This also fixes a few other misc issues:
- Fix `// check-stdout` for UI tests; previously it only worked for run-fail and compile-fail tests
- Add lint headers for tool lints, not just builtin lints
