[webauthn] Merged Pull Request: add indication of cross-origin operation in `collectedClientData`

equalsJeffH has just merged equalsJeffH's pull request 1276 for https://github.com/w3c/webauthn:

== add indication of cross-origin operation in `collectedClientData` ==
fixes #1271 #911

This webauthn PR is associated with w3c/webappsec-credential-management#138. It eliminates the `sameOriginWithAncestors` check from both `[[Create]]()` and `[[DiscoverFrom...]]()` and instead adds the inverse of it's value to `collectedClientData` in the form of the `crossOrigin` boolean.

Cross-origin usage is now gated upon feature policy, per w3c/webappsec-credential-management#138.  Credman+WebAuthn default behavior remains the same as before:  allowed in same-origin contexts, disallowed in cross-origin contexts. Cross-origin usage can now be attained by the RP webdev/author by explicitly setting the `publickey-credentials` feature policy.
