Recreate swapchain and use MAX_FRAMES_IN_FLIGHT

Several changes here
- use MAX_FRAMES_IN_FLIGHT
- recreate swapchain at appropriate points or events
- don't need sampler in shader for present because we don't have
  any other viewports to render yet. (scaling not implemented, etc)
- nothing to bind because nothing exists yet
- should be ready to implement imgui
