Re: [webauthn] "android-key" and "android-safetynet" are really basic attestation type support? (#1819)

I understand the logic behinds the Android Key Attestation. So, the attestation key (and certificate) shared across Android device and credential certificate for the user public key is signed by the attestation key, which makes sense that the trust model for this is basic".

As a results,

- The WebAuthn spec needs change Android Safetynet attestation trust model (attestation type) from **Basic** to **AnonCa**.
- The FIDO spec (registry) needs change Android Key attestation trust model from **AnonCa** to **Basic** which is referred by FIDO MDS.
