Remove vim modelines

We're deprecating vim modelines in favor of `.editorconfig`.

Removing vim modelines could be done using two one-liners. Most of the vim modelines
were followed by an empty line, so this one-liner took care of these ones:

```sh
rg '^# vim: .+\n\n' -l | xargs sed -i '/^# vim: /,+1d'
```

Then some of the vim modelines were followed by a pylint configuration line, so running
this one-liner afterwards took care of that:

```sh
rg '^# vim:' -l | xargs sed -i '/^# vim: /d'
```
