There is a discrepency between the string representation of C++ FunctionSchema and torchgen.model.FunctionSchema.
The latter will not add parenthesis around the returned types if that a single item,
but the C++ FunctionSchema always add the parenthesis.
Make them consistent so we can convert one type to the other via its string representation and parse method.

Summary:
After this, all combinations of {String frontend, Python AST Frontend}{Python 3-style type annotations, MyPy-style type comments}{Script method, Script function} should properly accept type annotations.
Possible TODOs:
- Clean up the functions marked HACK
- Clean up the Subscript tree-view to better match the Python AST versions
- Can we use this for Python functions? That's the only place annotations.get_signature() is still needed
