Re: [webauthn] Indicate resident key credential "preferred" during registration and find out what the authenticator offered (#991)

It doesn't require CTAP changes.

Platform will take care of this w.r.t CTAP communication. 
- `required`: Platform will send `rk=true` to the authenticator and will fail if that call fails.
- `preferred`: Platform will send `rk=true` to the authenticator and if that fails, will send another command to the authenticator with `rk=false` (or omit this parameter) 
- `discouraged`:  Platform will send `rk=false` (or omit this parameter) to the authenticator and if that fails, will send another command to the authenticator with `rk=true`
