WIP: IMPALA-13155: Smallify strings values in all Tuple::Deepcopy()

Currently "Tuple::DeepCopy(const TupleDescriptor& desc, char** data,
int* offset, bool convert_ptrs)" does not try to smallify string values,
although it could safely do that as it creates new string values. We use
that version of DeepCopy when we BROADCAST data between fragments, so
smallifying on that path can be beneficial.
