> Currently in {{AbstractStructVector#getPrimitiveVectors}}, only struct type
> child vectors will recursively get primitive vectors, other complex type like
> {{ListVector}}, {{UnionVector}} was treated as primitive type and return
> directly.
> For example, Struct(List(Int), Struct(Int, Varchar)) {{getPrimitiveVectors}}
> should return {{[IntVector, IntVector, VarCharVector]}} instead of
> [ListVector, IntVector, VarCharVector]
