        speed up new-run-webkit-tests unit tests

        Add a --no-record-results flag that turns off generating the JSON
        results file on every test run. Generating the file requires us to
        fetch the old results down from the bots, which can be slow. This
        flag is off by default.

        Reduce the sleep time in wait_for_threads_to_finish from 0.1s to 0.01s.

        These changes together shorten the test cycle from ~4.5s to ~1.5s
        - a 3x speedup.
