Fix retrieval of accurate refresh duration across multiple display screens.

- Add [CAMetalLayer screenMVK] extension method to retrieve screen.
- If the layer has a delegate view, use it to locate the screen, otherwise
  revert to iterating across windows, looking for the CAMetalLayer, to identify
  the window the layer is in, from which to retrieve the screen.
- Fix the iteration of the layer hierarchy, to accommodate that Apple may
  add superlayers to the CAMetalLayer under the covers.
- Update MoltenVK_Runtime_UserGuide.md to encourage the app to ensure the view
  is the delegate of the CAMetalLayer, to more efficiently access the screen.
