Re: [webauthn] add feature detection blurb... (#1208)

technically, according to credman's [section 7.1. Website Authors](https://www.w3.org/TR/credential-management-1/#implementation-authors), one only needs to check for `window.<necessary-credential-type>`, however I'm not a JS & client-side-dev expert.  AFAIK,  a user agent would need to implement all the things you're checking for in order to support "just"  `PublicKeyCredential` so your thorough check _ought_ to work correctly across various partial impls of crendential management?
