Remove remaining rmm/cuda_stream_view.hpp includes

[bdice]

Follow-up to #3129. Replaces the three remaining unused #include <rmm/cuda_stream_view.hpp> with #include <cuda/stream> in headers that only use cuda::stream_ref, and replaces the last rmm::cuda_stream::view() call (in tests/core/interruptible.cu) with the conversion to cuda::stream_ref. These APIs were removed in rapidsai/rmm#2552, so this fixes the build against current rmm nightlies.

📝 Summary

Summary by CodeRabbit

• Chores
  • Updated CUDA stream integration across linear algebra, matrix selection, and kernel launches. These changes do not alter the functionality available in those areas or introduce user-facing behavior changes. Existing workflows remain unchanged.

Walkthrough

Three C++ headers replace the RMM CUDA stream-view include with <cuda/stream>. In the interruptible test, capturing_stream::view() returns its stream member directly.
