vk/windows: Try to keep msq thread from ever stopping

- NVIDIA drivers hook into the msq before our nativeEvent handler. This means NV is aware of events before rpcs3 is aware of them and sometimes stops until a new event is triggered.
  If rpcs3 is inside a driver call at this time, the system will deadlock since the driver waits for msq which waits for the renderer which waits for the driver.
- Use explicit hook management to control window events
- Add fence timeout to attempt detection of surface loss events
