[C++][Dataset] Selecting a StringView column ("project") of a Dataset crashes

### Describe the bug, including details regarding any error messages, version, and platform.

Using the same dataset created in the top post of https://github.com/apache/arrow/issues/39637:

```
import pyarrow.dataset as ds
dataset = ds.dataset("test_string_view/", format="ipc")

>>> dataset.schema
Out[26]:
a: int64
b: string_view

>>> dataset.to_table(columns=["a"])
pyarrow.Table
a: int64
----
a: [[1,2,3]]

>>> dataset.to_table(columns=["b"])
Segmentation fault (core dumped)
```

So selecting the integer column works fine, but when selecting the string_view column, it crashes.
