[ruff] Implement mutable-fromkeys-value (RUF024) (#9597)

Browse source 
## Summary

Implement rule `mutable-fromkeys-value` (`RUF023`).

Autofixes

```python
dict.fromkeys(foo, [])
```

to

```python
{key: [] for key in foo}
```

The fix is marked as unsafe as it changes runtime behaviour. It also
uses `key` as the comprehension variable, which may not always be
desired.

Closes #4613.

## Test Plan

`cargo test`
