Generalize comment-after-bracket handling to lists, sets, etc. (#6320)

## Summary

We already support preserving the end-of-line comment in calls and type
parameters, as in:

```python
foo(  # comment
    bar,
)
```

This PR adds the same behavior for lists, sets, comprehensions, etc.,
such that we preserve:

```python
[  # comment
    1,
    2,
    3,
]
```

And related cases.
