Various XR fixes
Mostly making sure we expose the correct things on the XRSession interface.
No backend currently supports visibility state changes, and it's tricky to do this for Hololens because currently we must pump the event loop to notice these events, and only rAF pumps the event loop right now, which means that applications which choose to stop running rAF when blurred will have a problem.
