Re: [webauthn] restrict WebAuthentication API to only top level browsing context

NOTE: this issue was _at least_ "improved" by this recent merged-in change to [CredMan](https://w3c.github.io/webappsec-credential-management/):  

  PR w3c/webappsec-credential-management#114 
  "[Remove the blanket restriction against nested usage](https://github.com/w3c/webappsec-credential-management/pull/114)".  

We _could_ declare that this "[sameOriginWithAncestors](https://w3c.github.io/webappsec-credential-management/#same-origin-with-its-ancestors)" approach "fixes" this issue if we feel that RPs do not need the functionality of being able to declare "top-level only" or not, and having [sameOriginWithAncestors](https://w3c.github.io/webappsec-credential-management/#same-origin-with-its-ancestors) as the default functionality is sufficient. 

WDYT?
