Is your feature request related to a problem? Please describe.

CUDA stream protocol can help libraries to interact with raw cuda streams in a natural way, for example, a framework can check hasattr(stream, "__cuda_stream__") then fetch the returned stream and pass to arguments that needs stream in places like DLPack.

The nice thing about such pattern is the downstream package do not need explicitly do isinstance(stream, StreamClass) and also do not need to introduce explicit dep to related stream classes.

It would be nice for cuda-python stream classes to implement CUDA stream protocol

Describe the solution you'd like

• cuda.bindings.driver.CUstream support CUDA stream protocol
