create and arrow utility to materialize ScanResult into record batches

[zachschuermann]

in many places we've duplicated the following (copied from delta-sharing's) arrow materialization, should probably just create some utility and expose it behind an arrow feature flag

fn try_create_record_batch_iter(
    results: impl Iterator<Item = DeltaResult<ScanResult>>,
    result_schema: ArrowSchemaRef,
) -> RecordBatchIterator<impl Iterator<Item = Result<RecordBatch, ArrowError>>> {
    let record_batches = results.map(|res| {
        let scan_res = res.and_then(|res| Ok((res.full_mask(), res.raw_data?)));
        let (mask, data) = scan_res.map_err(|e| ArrowError::from_external_error(Box::new(e)))?;
        let record_batch: RecordBatch = data
            .into_any()
            .downcast::<ArrowEngineData>()
            .map_err(|_| ArrowError::CastError("Couldn't cast to ArrowEngineData".to_string()))?
            .into();
        match mask {
            Some(mask) => filter_record_batch(&record_batch, &mask.into()),
            None => Ok(record_batch),
        }
    });
    RecordBatchIterator::new(record_batches, result_schema)
}
