[C++][Parquet] Predicate pushdown through arrow::dataset::ScanBuilder::Filter() not available on list fields

### Describe the enhancement requested

This enhancement request would be a continuation of the previous enhancement done in https://github.com/apache/arrow/pull/39065 to support nested fields where the nesting type is a struct.

Here I would like to apply a predicate pushdown on the ``x`` subfield of a ``list>``

```
required group field_id=-1 schema {
optional binary field_id=-1 id (String);
optional group field_id=-1 geometry (List) {
repeated group field_id=-1 list {
optional group field_id=-1 element {
required double field_id=-1 x;
required double field_id=-1 y;
}
}
}
}
```

When trying to apply the following expression as parquet::Dataset::ScanBuilder::Filter(),
```
auto fieldRefX = arrow::FieldRef(arrow::FieldRef("geometry", "element"), "x");
expression =cp::less_equal(cp::field_ref(arrow::FieldRef(fieldRefX)), cp::literal(m_sFilterEnvelope.MaxX))
```

I get the following error: ``nested paths only supported for structs``

(I tried to remove that check, but I then get the following error: ``Function 'struct_field' has no kernel matching input types (list>)``)

Beyond the technical difficulties in implementing that, I guess there's a potential ambiguity of what such filtering means. Would that mean that a row is selected if all corresponding entries in the list match the predicate, or if just one would. For my use case (spatial filtering directly applied on [GeoArrow struct/separated encoded geometry columns](https://geoarrow.org/format.html), for non-Point geometry types, in GeoParquet files), the later would be what I'm looking for.
