 Two kind-polymorphism fixes (Trac #10122)

 * The original fix was to improve the documentation, in
   line with the suggestions on Trac #10122

 * But in doing so I realised that the kind generalisation in
   TcRnDriver.tcRnType was completely wrong.  So I fixed that
   and updated Note [Kind-generalise in tcRnType] to explain.
