> Allow Complex Types to be vectorized (since HIVE-16207: "Add support for Complex Types
in Fast SerDe" was committed).
> Add more classes we vectorize AVG in preparation for fully supporting AVG GroupBy.  In
particular, the PARTIAL2 and FINAL groupby modes that take in the AVG struct as input.  And,
add the COMPLETE mode that takes in the Original data and produces the Full Aggregation for
completeness, so to speak.
