[webauthn] RP ops registration step 16 is missing a case for None attestation (#1136)

emlun has just created a new issue for https://github.com/w3c/webauthn:

== RP ops registration step 16 is missing a case for None attestation ==
Step 16 of [ยง7.1. Registering a New Credential](https://w3c.github.io/webauthn/#registering-a-new-credential) currently reads:

>Assess the attestation trustworthiness using the outputs of the verification procedure in step 14, as follows:
>- If self attestation was used, check if self attestation is acceptable under Relying Party policy.
>- If ECDAA was used, verify that the identifier of the ECDAA-Issuer public key used is included in the set of acceptable trust anchors obtained in step 15.
>- Otherwise, use the X.509 certificates returned by the verification procedure to verify that the attestation public key correctly chains up to an acceptable root certificate.

This is missing a case for None attestation, which would be almost identical to (or, alternatively, merged with) that for self attestation:

>- If none attestation was used, check if no attestation is acceptable under Relying Party policy.
