support generate template for use with UnityResolve.

Though there's already c++ scaffolding support but it's not really handful.
It might be better to support generating (function?)template for use with UnityResolve

Hi, you propose to change the codegen for a specific library. This causes 3 issues: a) you need to keep track library api changes, b) you hardly need all classes at runtime, although DCE of C++ compiler solves this problem (I'm still not sure about it), and most importantly c) not everyone uses this library, which creates additional difficulties. IMHO the C++ scaffolding inspector should be removed at all
