[host] windows: fix graceful exit
We were using an auto-reset event to signal the mousehook exit. This was fine when there was only one thread, but with the addition of the update thread, only one thread is signaled, causing the wait to last forever. The fix is switching to a manual reset event and call ResetEvent after the threads have exited.
