1. Fix help display for non-String RawRepresentables …

   RawRepresentable types that have a non-String raw value are having
   values displayed in the help screen by converting the RawRep value
   into a string. However, these values are by default parsed by their
   raw value, so we should use that for display instead.
   
   This is accomplished by adding a defaultValueDescription
   implementation for all ExpressibleByArgument-conforming RawValue
   types, and then basing the allValues implementation on that.
   This generalizes the existing overloads for String-based RawRep types,
   while also allowing users who customize their ExpressibleByArgument
   implementation to provide the correct help value for clients.
