This PR fixes a bug in the multipolygon geometry iterator. The geometry iterator was returning part iterators by mistake, which masked an issue that we were patching out in rapids-cmake's CCCL. See rapidsai/rapids-cmake#511. With this fix, we can remove that patch from rapids-cmake's CCCL: rapidsai/rapids-cmake#640 Authors: - Bradley Dice (https://github.com/bdice) - Paul Taylor (https://github.com/trxcllnt) Approvers: - Michael Schellenberger Costa (https://github.com/miscco) - Mark Harris (https://github.com/harrism) - Michael Wang (https://github.com/isVoid) - Paul Taylor (https://github.com/trxcllnt) URL: #1402

While upgrading CCCL, we ran into a test failure in cuSpatial. We added a patch to revert some changes from CCCL but the root cause was a bug in cuSpatial. I have fixed that bug here: rapidsai/cuspatial#1402 Once that PR is merged, we can remove this CCCL patch.

Description
Something is going wrong in
thrust::copy, so I am adding a patch to revert NVIDIA/cccl#211. This will fix the failing tests for rapidsai/cuspatial#1315.This is where it's failing, with
thrust::copy:https://github.com/rapidsai/cuspatial/blob/8e8fa0689339c0288746b01a8af66fb599f5c770/cpp/tests/range/multipolygon_range_test.cu#L800
CI log: https://github.com/rapidsai/cuspatial/actions/runs/7229405991/job/19700477218?pr=1315#step:7:3280
I traced it down to this CCCL PR - note that
thrust::transform(..., thrust::identity{})works, but the newthrust::copycode path in NVIDIA/cccl#211 that callscudaMemcpyAsyncdoesn't work for some reason. I was not able to identify the exact reason why that PR causes the failure. Patching this out will unblock RAPIDS and let us migrate forward with CCCL 2.2.0.This helps with #502.
