IMPALA-6669: Remove Parquet NeedsSeedingForBatchedReading()

I noticed that we could remove this part of the interface and instead
do the "seeding" in ParquetColumnReader::Read*ValueBatch(). It should
be easier to understand with level reading and consumption happening
driven by the same function instead of split between files.

Testing:
Ran core tests. This code path should be thoroughly exercised by
the regular scanner tests.
