Visit TypeVar and NewType name arguments

[charliermarsh]

Summary

Given NewType(x, y), we weren't visiting x at all. I think this is because x is typically a string constant (the name of the NewType), and we wanted to avoid treating it as a forward reference -- but we have support for that kind of traversal anyway.

Closes #4623.
