Describe the enhancement requested

This is a subsequent issue of #41909.

We don't add support for ordering in #41909. But Apache Parquet has ordering information:
https://github.com/apache/parquet-format/blob/5a5c8948e60770f8a8356a8f5e616d5ae1079d4b/src/main/thrift/parquet.thrift#L953-L1001

We need to add support for ordering to assign statistics read from Apache Parquet data to Apache Arrow arrays.
