Remove get_line() and get_column() functions (#14071)

When I was working on a different PR for Mypy, I came across these
functions:

```python
    def get_line(self) -> int:
        """Don't use. Use x.line."""
        return self.line

    def get_column(self) -> int:
        """Don't use. Use x.column."""
        return self.column
```

So I just went ahead and removed them.
