Re: [webauthn] Add "Credential Manager Trust Group (CMTG) Key" extension (#2377)

@timcappalli at the risk of being wrong again again: did we forget to add JSON serialization for CMTG? We don't seem to have a partial [AuthenticationExtensionsClientInputsJSON](https://w3c.github.io/webauthn/#dictdef-authenticationextensionsclientinputsjson) dictionary defined for this extension (or [AuthenticationExtensionsClientOutputsJSON](https://w3c.github.io/webauthn/#dictdef-authenticationextensionsclientoutputsjson)).
