Description

Currently building an empty nested column is done in Java layer, the performance is not good, and it creates a lot of unnecessary Java objects.
We should move it to the native after figuring out a way to pass the nested data type to the native.

This requirement is from https://github.com/rapidsai/cudf/pull/8173#discussion_r627530793
