Re: [webauthn] Provide an explicit way to opt out of multi-device syncing/backups (#1714)

> or go to an open ecosystem where every sufficiently certified device is allowed, and DPK is always requested to trigger an explicit device sync flow: either reject the attempt because a new device is detected, or trigger the explicit enrolment of the new device through its DPK.

This would indeed be a way to enforce the current, non-syncing behavior if I understand it correctly.

Given that DPK is accepted as proposed, this proposal is then mostly syntactic sugar on the RP/API consumer side.

On the implementor side, it still seems useful to have, e.g. for UX purposes (as there is no point in uploading and showing a credential in a user's syncing account if it effectively can never be used for logins).
