Reintroduce ProMotion support (#7347)

This re-introduces the changes of #7305 but this time we create a
display link using the `NSScreen` associated with the window. We're
hoping we'll get these frame requests more reliably, and this seems
supported by the fact that awakening my laptop restores the frame
requests.

Release Notes:

- See #7305.
