[Python][Parquet] `TypeError` with list-type columns in `pd.read_parquet` if the list column is not loaded.

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

This follows on from a comment I left on #39914. Loading will fail if `columns=` is specified and there is a list-type column which is not in the specified `columns=` argument:

```python
import pandas as pd
import pyarrow as pa

a = pd.Series(pa.array([[1, 2, 3]]), dtype=pd.ArrowDtype(pa.list_(pa.int64())))
b = pd.Series(pa.array([1]), dtype=pd.ArrowDtype(pa.int64()))
df = pd.DataFrame({"a": a, "b": b})
df.to_parquet("test.parquet", index=False)

pd.read_parquet("test.parquet", dtype_backend="pyarrow") # Works
pd.read_parquet("test.parquet", dtype_backend="pyarrow", columns=["a"]) # Works
pd.read_parquet("test.parquet", dtype_backend="pyarrow", columns=["b"]) # Fails
```

Results in
```
