Merge bitcoin/bitcoin#33319: ci: reduce runner sizes on various jobs

5eeb2fa ci: reduce runner sizes on various jobs (will)

Pull request description:

  These jobs can likely use reduced runner sizes to avoid wasting our CPU quota, as much of the long-running part of the job is single-threaded.

  This will also give us more (job) parallelisem from the same number of CPU that we are using.
