## Summary
Closes#9319, implements the [`SIM911` rule from
`flake8-simplify`](https://github.com/MartinThoma/flake8-simplify/pull/183).
#### Note
I wasn't sure whether or not to include
```rs
if checker.settings.preview.is_disabled() {
return;
}
```
at the beginning of the function with violation logic if the rule's
already declared as part of `RuleGroup::Preview`.
I've seen both variants, so I'd appreciate some feedback on that :)
