chore: add workflow to trigger cc (#22060)

Superseeds #22055

When working on capture checking, error messages might change if we
compile using the cc library or the non-cc library.
Usually, this errors are not catched when running the workflows on each
PR and are only detected on nightly builds.
The following PR introduces a new workflow that is trigger on each merge
to main and on each change to cc related files.
