[SDL 0308] Add a Reason Parameter to All Protocol NAKs

Proposal: Add a Reason Parameter to All Protocol NAKs

As a maintainer of an app library, it is often difficult to understand why Core has NAKed a protocol message. Most NAKs currently have a rejectedParams parameter, but in practice, this has not been enough information to determine why a NAK has occurred and properly alert the developer. In place of the rejectedParams parameter, the RegisterSecondaryTransportNAK has a reason parameter to describe the failure reason. This is a better approach and we should expand it to all NAK parameters.
