Break global and nonlocal statements over continuation lines (#6172)

## Summary

Builds on #6170 to break `global` and `nonlocal` statements, such that
we get:

```python
def f():
    global \
        analyze_featuremap_layer, \
        analyze_featuremapcompression_layer, \
        analyze_latencies_post, \
        analyze_motions_layer, \
        analyze_size_model
```

Instead of:

```python
def f():
    global analyze_featuremap_layer, analyze_featuremapcompression_layer, analyze_latencies_post, analyze_motions_layer, analyze_size_model
```

Notably, we avoid applying this formatting if the statement ends in a
comment. Otherwise, the comment would _need_ to be placed after the last
item, like:

```python
def f():
    global \
        analyze_featuremap_layer, \
        analyze_featuremapcompression_layer, \
        analyze_latencies_post, \
        analyze_motions_layer, \
        analyze_size_model  # noqa
```

To me, this seems wrong (and would break the `# noqa` comment). Ideally,
the items would be parenthesized, and the comment would be on the inner
parenthesis, like:

```python
def f():
    global (  # noqa
        analyze_featuremap_layer,
        analyze_featuremapcompression_layer,
        analyze_latencies_post,
        analyze_motions_layer,
        analyze_size_model
    )
```

But that's not valid syntax.
