Silly question: Why is this not std::copy() to back_inserter{stream_refs}?

In `@cpp/libcudf_streaming/benchmarks/streaming/ndsh/concatenate.cpp`:
- Around line 59-60: Adapt both stream arguments before calling
rapidsmpf::cuda_stream_join: in concatenate.cpp at lines 59-60 and join.cpp at
lines 64-69, pass concat_stream and gather_stream through
cudf_streaming::detail::as_rmm_cuda_stream_view so the single-stream overload
receives rmm::cuda_stream_view.
In `@cpp/libcudf_streaming/include/cudf_streaming/detail/stream_adapters.hpp`:
- Around line 27-31: Add direct unit coverage for the stream adapter scalar
overloads and as_rmm_cuda_stream_view_range, exercising both cuda::stream_ref
and rmm::cuda_stream_view inputs and verifying the adapted results. Add the
required unit benchmark alongside these tests, reusing the existing test and
benchmark conventions.

Add direct tests for the stream adapters.
Add unit tests for both scalar overloads and as_rmm_cuda_stream_view_range, using cuda::stream_ref and rmm::cuda_stream_view ranges. Add the required unit benchmark.

All non-Spark checks have passed on the latest head ( I opened NVIDIA/cudf-spark-jni#5053 as a current-main replacement for the conflicting NVIDIA/cudf-spark-jni#5014. #5053 is green and mergeable, but still needs review before this Spark check can be rerun successfully here. |

Marking as DO NOT MERGE until we get cudf-spark copacetic with upstream again (so that we can properly validate with CI on this branch) and sort out how we want to deal with stream pools (the interface with rapidsmpf in this PR is a bit noisy because of the stream pool boundary involving stream_ref<->cuda_stream_view interchange). |

Description
This Wave 2 follow-up to #23691 migrates the central stream helpers from
rmm::cuda_stream_viewtocuda::stream_ref, includingget_default_stream(),default_stream_value,fork_streams, andjoin_streams.It also updates the direct Java, pylibcudf, and libcudf_streaming call sites whose method calls depend on those helper return types.
rmm::cuda_streamownership remains unchanged.This should land after the Wave 1 downstream
stream_refPRs.Replaces the fork PR vyasr#9.
Contributes to #23636
