Re: [webauthn] Identify which items in creation and assertion options are client UI/UX hints (#1618)

Of course if the parameters are altered before they reach the call into the client API then the result may be different, I don't think we should have to point that out. The RP operations also contain an explicit step for verifying the UV flag of the response.

As for the [`authenticatorAttachment`](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#dom-authenticatorselectioncriteria-authenticatorattachment) parameter, I agree we should make it clearer that the actual outcome might be determined using [`getTransports()`](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#dom-authenticatorattestationresponse-gettransports). The [`ResidentKeyRequirement`](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#enumdef-residentkeyrequirement) description similarly points to the [`credProps` extension](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#credprops) for checking whether the new credential ended up discoverable.
