[webauthn] Justify differences in TPM Attestation Verification procedures in WebAuthn versus TCG specifications

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

== Justify differences in TPM Attestation Verification procedures in WebAuthn versus TCG specifications ==
As per reference [TPMv2-Part1], Section 31.2, a 'Standard Attestation Structure' is defined.  Several of the defined fields are not reflected in verification procedures (e.g. QualifiedSigner, clockInfo, firmwareVersion) in Sec. 7.3 of Webauthn (WD-04).  The text should at least highlight why a verifier can ignore these fields, and whether an attestation without these fields should be considered invalid.
