Fetch vulkan shader printf messages from a pristine replayed state

* For draws/dispatches that aren't pure - i.e. modify state that they read from
  - we need to be sure we don't replay the action before running it to fetch
  feedback. For that reason we need to replay up to the action first, then fetch
  feedback.
