Partially duplicates reporter logic; reporter could auto-apply actions, maybe keying off diagnostic ID.
Instead of testing whether to emit actions by probing suppressions, just let the reporter apply LintWarning actions when the warning is actually reported.

Fixes #24009
Why was the ticket worth tackling?
-Wconfallows users to control which optional warnings are reported, which is convenient for limiting noise and essential under-Werror. However, unwanted lints are destructive under-rewrite.How I fixed it
Instead of gating at the lint (for unused imports), enhance the reporter to apply code actions for lint warnings.
Why is this PR worth reviewing?
This PR turns out to be more complex in UX than in code.
What's the worse that could happen?
The code action in
CheckUnusedis always emitted when the lint is enabled. That could be noisy in an interactive environment that displays quickfixes.
