…empty parquet row group bug (#45740) ### What problem does this PR solve? Problem Summary: Checks if the given column has a dictionary page. This function determines the presence of a dictionary page by checking the `dictionary_page_offset` field in the column metadata. The `dictionary_page_offset` must be set and greater than 0, and it must be less than the `data_page_offset`. The reason for these checks is based on the implementation in the Java version of ORC, where `dictionary_page_offset` is used to indicate the absence of a dictionary. Additionally, Parquet may write an empty row group, in which case the dictionary page content would be empty, and thus the dictionary page should not be read. See https://github.com/apache/arrow/pull/2667/files
