- Fix bug when PARQUET_FILTER_PUSHDOWN_ENABLED=false
- Evaluate time cost when PARQUET_FILTER_PUSHDOWN_ENABLED=true/false
- If NATIVE_IO_WRITE_MAX_ROW_GROUP_SIZE is small, time cost of PARQUET_FILTER_PUSHDOWN_ENABLED=true/false are almost equal
- If NATIVE_IO_WRITE_MAX_ROW_GROUP_SIZE is large, case of PARQUET_FILTER_PUSHDOWN_ENABLED=true will use more time than negative case
