Allow collapsed-ellipsis bodies in other statements (#8499)

Browse source 
## Summary

Black and Ruff's preview styles now collapse statements like:

```python
from contextlib import nullcontext

ctx = nullcontext()
with ctx: ...
```

Historically, we made an exception here for classes
(https://github.com/astral-sh/ruff/pull/2837). This PR extends it to
other statement kinds for consistency with the formatter.

Closes https://github.com/astral-sh/ruff/issues/8496.
