Re: [webauthn] Add RP conformance section on ignoring attestation

Thanks for writing this up @emlun. This appears to be useful info that we do not already address. Though, it seems to me to be more security considerations material than conformance. 

In looking through it I notice that we probably ought to explicitly address the case of "none" attestation in the [Registering a new credential](https://www.w3.org/TR/2018/WD-webauthn-20180306/#registering-a-new-credential) RP ops subsection, at least in step 14 (since the "none" attStmt format is the only one without a sig to verify).

There's various polishing and terminological fixes I'd offer but will wait on doing so since I'm betting we'll address this issue & PR for PR-milestone and we're presently still trying to attain  CR.  thanks again.
