* Fix extracting CUDA stream in cub::DeviceTransform #6204 changed cub::DeviceTransform APIs from taking cudaStream_t to environments. Special handling preserved support for cudaStream_t. However, user-provided stream types with conversion operators to cudaStream_t were now queried as environments, failing to return a stream. * Properly use `get_stream` in device transform We should not have a special overload for the `get_stream` overload but should ensure that we can pass types that are convertible to `::cudaStream_t` and extract that stream I have expanded the get_stream CPO to accept a `::cudaStream_t __stream` so that we can work with those types Co-authored-by: Michael Schellenberger Costa <[email protected]> (cherry picked from commit 31f8a13)
