Re: [webauthn] devicePubKey → supplementalPubKeys (#1957)

@sbweeden I wasn't thinking of signaling a change of control based on device biometrics.   
I was thinking that the provider key would not be exported to a different subscriber account within the same provider.

I think that explicitly moving the credential into another subscribers account should not carry with it the provider scope key.   Or if it is carried arcoss we need a user scope where the supplemental key is unique to the combination of Account, RP, Provider.    

I think that a lot of RP will be forced via regulation to do some additional step up each login if they can't detect a change of subscriber account.
