Rollup merge of #140086 - ChrisDenton:backoff, r=petrochenkov

If creating a temporary directory fails with permission denied then retry with backoff

On Windows, if creating a temporary directory fails with permission denied then use a retry/backoff loop. This hopefully fixes a recuring error in our CI.
