This is another attempt at CL 558895, but without adding stale pollDescs protection, which deviates from the original goal of the CL and adds complexity without proper testing. It is currently not possible to distinguish between a netpollBreak, an internal/poll WSA operation, and an external WSA operation (as in #58870). This can cause spurious wakeups when external WSA operations are retrieved from the queue, as they are treated as netpollBreak events. This CL makes use of completion keys to identify the source of the event. While here, fix TestWSASocketConflict, which was not properly exercising the "external WSA operation" case.
