Replace <cuda/stream_ref> includes with <cuda/stream> (#2513)

CCCL deprecated the `<cuda/stream_ref>` header; `cuda::stream_ref` is now provided by `<cuda/stream>`. This PR switches every `#include <cuda/stream_ref>` to `#include <cuda/stream>` so RMM builds against newer CCCL.

The `cuda::stream_ref` type is unchanged. This was observed in rapids-cmake CI: https://github.com/rapidsai/rapids-cmake/actions/runs/31745925779/job/94600794610?pr=1073
