If we do need ```Object[]```, specialized ```GenericArrayData``` would not
help us due to three reason.
1. To pass ```Object[]``` cannot exploit specialized ```GenericArrayData```
since signature of generalized as ```Object[]```. Each element could have a
value with different classes.
2. To pass ```Object[]``` causes boxing at an assignment in the generated
code (e.g. Line 064 of "Generated code before applying this PR" in
https://github.com/apache/spark/pull/13704)
3. To keep ```Object[]``` causes unboxing at
```GenericArrayData.get<PrimitiveType>()``` or
```GenericArrayData.to<PrimitiveType>Array()``` in the generated code (e.g.
Line 064 of "Generated code before applying this PR" in
https://github.com/apache/spark/pull/13704).
