Description

**Is your feature request related to a problem? Please describe.**
pandas and Polars support binary equality between two list columns or two struct columns xref https://github.com/rapidsai/cudf/issues/6040. Currently `binaryop::binary_operation` is not supported with these columns using `NULL_EQUALS` or `NULL_NOT_EQUALS`. To support this operation in cuDF classic and cudf-polars, it would be ideal if libcudf supported this operation.

**Describe the solution you'd like**
The ability for `binaryop::binary_operation` to support a lhs and rhs of both list or struct columns with an op of `NULL_EQUALS` or `NULL_NOT_EQUALS`.

**Describe alternatives you've considered**
This could be implemented in Python in cuDF classic and cudf_polars, but the implementation would not be able to be shared between both libraries.

**Additional context**
https://github.com/rapidsai/cudf/pull/11609#issuecomment-2093875686 describes the possible change needed to support this.
