[SPARK-15639][SQL] Try to push down filter at RowGroups level for parquet
reader
## What changes were proposed in this pull request?
When we use vecterized parquet reader, although the base reader (i.e.,
`SpecificParquetRecordReaderBase`) will retrieve pushed-down filters for
RowGroups-level filtering, we seems not really set up the filters to be pushed
down. This patch tries to set the filters for pushing down to configuration for
the reader.
## How was this patch tested?
Existing tests should be passed.
