WIP IMPALA-14794: Implement small string optimization in Parquet scanner
TODO:
-do not copy the IO buffer for output batches if there are only small
strings (Dictionary encoded case is remaining)
-measure performance (can measure with small strings in dictionary, or
small strings without dictionary)
-test?
-test that page data is not actually attached to the tuple when
there are only small strings?
