… generation ### What changes were proposed in this pull request? - Parquet version `1.13.1` has a fix for [PARQUET-2161](https://issues.apache.org/jira/browse/PARQUET-2161) which allows splitting the parquet files when row index metadata column is selected. Currently the file splitting is disabled. Enable file splitting with row index column. ### Why are the changes needed? Splitting parquet files allows better parallelization when row index metadata column is selected. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Uncomment the existing unittests. Closes #40728 from vkorukanti/SPARK-39634.
