[3.13] gh-117657: Log TSAN warnings to separate files and archive them (GH-118747) (#118931)

This ensures we don't lose races that occur in subprocesses or
interleave races from workers running in parallel.

Log files are collected and packaged into a zipfile that can be
downloaded from the "Artifacts" section of the workflow run.
(cherry picked from commit b88889e9ffd7b2d2bdac75aecbf14e37fd68e337)
