[zxwait] Wait for done when canceled and closed Prior to this change, canceling pending waiters that were waiting for signals on a closed handled would leave "lingering" packets in the Port's queue. This would occasionally cause future waits to panic as the "done" channel was being closed twice. This CL flags waitingGs whose pending waiters have been canceled, which prevents double cancellation. This enables `Wait` to properly drain the `done` channel when it observes ctx cancellation for waits on a closed handle.
