Re: [webauthn] Add isPlatformAuthenticatorReady function to the API surface

wrt [my recent comment above](https://github.com/w3c/webauthn/pull/379#issuecomment-319226748)...

@AngeloKai [originally said](https://github.com/w3c/webauthn/pull/379#issue-214232061):
> ...if we don't resolve the promise, developers won't be able to react based on user saying no. In addition, web developers are interested in having at least a control over the UI being shown.

ok, now I think I'm getting what @AngeloKai is saying -- to test my understanding: 

if one crafts this method as @mikewest suggested such that it does not return a result and an affirmative answer is signaled by simply resolving the promise, and otherwise (no platform authnr available, user never answered, universe heat death, etc.) it never resolves, then there are not signals for crafting UX that can discriminate between success and various "failure" or "uh, i didn't see the prompt...." etc. cases.  Yes?
