Review comment:
This is a good question, but it seems that the filter pushed down in
DataSource V1 does not contain the filter related to partition columns too.
The `dataFilters` use to construct `FileSourceScanExec` and pass to
`ParquetFileFormat.buildReaderWithPartitionValues` to build `pushed` filters
also filtered out partition filters, am I right?
