(PUP-514) Add support for opt-in typing of define/class parameters

This makes define and class parameters support optionally typed
parameters when using the future parser. The type expressions
are evaluated by the Pops Bridge when parameters are transformed t 3x.
The 3x parameters are not aware of type information (they are encoded as
arrays), and changes to all the logic that deals with parameters turned
on to not be a good design. The resource type and resource is instead
made aware of the opt-in types via a separate param-name to type map
that it applies in the validation step that was already performed.
