IMPALA-3629: Codegen TransferScratchTuples() in hdfs-parquet-scanner

We currently don't do any codegen in the hdfs-parquet scanner,
which limits performance. This patch codegens conjunct evalution
using CodegenEvalConjuncts and cross-compiles TransferScratchTuples,
replacing the calls to EvalConjuncts in it with the codegend version.
