Remove lists::drop_list_duplicates (NVIDIA#11236)

This PR completely removes `cudf::lists::drop_list_duplicates`. It is replaced by the new API `cudf::list::distinct` which has a simpler implementation but better performance. The replacements for internal cudf usage have all been merged before thus there is no side effect or breaking for the existing APIs in this work. Closes rapidsai/cudf#11114, rapidsai/cudf#11093, rapidsai/cudf#11053, rapidsai/cudf#11034, and closes rapidsai/cudf#9257.
