Looks good to me. We can merge this after testing at least a few of RAFT, cuML, cuGraph, etc. |

RAFT PR: rapidsai/raft#2098 builds are good |

I think the valid builds in raft/cudf/cugraph are sufficient that this PR won't break anything. |

Patch both CCCL and CUCO to have only internal linkage. For cuco I am working on upstreaming these changes ( NVIDIA/cuCollections#422 ). Once that is accepted and we have validated that moving cuco is stable ( e.g. changes around `cuco::experimental::static_set` ) we can drop this patch set. For cccl the long term fix is to move to CCCL 2.3+, but due to issues ( NVIDIA/cccl#1249, maybe others ) that isn't viable for the 24.02 timeframe. Since the CCCL changes mean C++ and CUDA sources have non compatible ABI's, we need to specify `THRUST_DISABLE_ABI_NAMESPACE` and `THRUST_IGNORE_ABI_NAMESPACE_ERROR` so that we don't change ABI in rapids-cmake consumers since they expect 2.2 behavior.

This is to remove the row conversion code from libcudf. It was move from spark-rapids-jni (by #14664) to temporarily workaround the issue due to conflict of kernel names that causes invalid memory access when calling to `thrust::in(ex)clusive_scan` (NVIDIA/spark-rapids-jni#1567). Now we have fixes for the namespace visibility issue (by marking all libcudf kenels private in rapidsai/rapids-cmake#523 and NVIDIA/cuCollections#422) and need to move back the code. Closes #14853.
