* Kindsys: Replace DeclForGen with kindsys.Kind
DeclForGen was always unnecessary - it just wasn't obvious on initial
implementation, when we were focused on generating unique types for each
core kind. This removes it, considerably simplifying interactions with
kindsys - virtually everything now just relies on kindsys.Kind and its
derived interfaces.
