[red-knot] Resolve function annotations before adding function symbol (#13084)

This PR has the `SemanticIndexBuilder` visit function definition
annotations before adding the function symbol/name to the builder.

For example, the following snippet no longer causes a panic:

```python
def bool(x) -> bool:
    Return True
```

Note: This fix changes the ordering of the global symbol table.

Closes #13069
