Support typedef overwrites in class scopes 

It is possible to declare a new typedef that shadows an existing typedef in
a higher level scope. E.g.

```
typedef int T;
class C;
  typedef real T;
endclass
```

In the current implementation this works for scopes that are not class
scopes.

Update the parser to also support this in class scopes by re-using the
existing parser rule that is used for the other scopes.

Reusing the existing rule also adds support for class forward typedes
inside classes.
