Visualizer for clang::FunctionProtoType
Displays return type and parameters for the Function Protoype object in the
Locals window. For example, the prototype `int(double, A *)` displays as
```
T Int(Double, struct A *)
|-ReturnType Int
|-Parameter Types Double, struct A *
|-[0] BuiltinType {Double}
|-[1] PointerType {struct A *}
| /* More stuff */
```
