Add "NewReference" for Global and Local

[jwhpryor]

It's legitimate to want to copy a local or global and this should be supported.

e.g. a syntax like:
LocalObject<kClass> obj { obj, ShallowCopy{} };

This would be very similar to GlobalObject creation as a source for copying implementation from.

Doh, I actually may have taken care of the bulk of this literally earlier today (search for CreateCopy) 🤦🏻‍♂️.

That said, there's actually no meaningful E2E test. That would be both helpful, and probably a good intro to project.

Alternatively, #2 is unlikely to be finished soon, and is likely also a good spot to start.
