In general this moves in the direction of dealing more with Identifier instances instead of TypeAnnotation instances.
This ended up being a larger refactor than I had hoped, but at a high level it does the following:
- Adds the TypeAnnotationCode/NamedTypeAnnotationCode/FunctionTypeAnnotationCode classes
- Change the TypeResolver api to have a single 'resolve' method, which takes a TypeAnnotationCode argument
- Makes ParameterCode/TypeParameterCode take more structured arguments
- Update the CFE code to be able to resolve NamedTypeAnnotationCode instances instead of TypeAnnotation instances
- Also deletes some unnecessary Code classes.
Note that supporting FunctionTypeAnnotationCode instances looks like it will be some more work in the CFE.
