[orc-rt] Add CallableTraitsHelper, refactor WrapperFunction to use it. (#161761) CallableTraitsHelper identifies the return type and argument types of a callable type and passes those to an implementation class template to operate on. The CallableArgInfo utility uses CallableTraitsHelper to provide typedefs for the return type and argument types (as a tuple) of a callable type. In WrapperFunction.h, the detail::WFCallableTraits utility is rewritten in terms of CallableTraitsHandler (and renamed to WFHandlerTraits).
