.cirlceci: Remove setup job (#39081)
Summary:
The setup job isn't really what we need anymore so let's get rid of it
and remove the single point of failure from our build pipeline.
Should also resolve issues with CircleCI where re-run workflow from failed would trigger an entire re-run instead of only jobs that we actually want to re-run.
