[kernel][exceptions] fix thread kill/exception race Previously, if a caller killed a thread then immediately resumed from exception (e.g. via closing the exception port), there was a chance that the resume status would take precedence and we would keep processing the exception on a killed thread. This CL adds an additional check so that if the thread is both resumed and killed, the kill will always take precedence. This is difficult to test in an automated unittest so these new tests just run for 1 second and it'll show up as flake in the bots if the bug returns. To test manually, insert a sleep in the kernel between sending the exception and waiting for the response to lengthen the race window.
