set stream everytime when we get a cuBlas handle (#31537)
Summary:
I don't see any reason for not doing so, because it is a common error that people forget to set the stream. And I don't think there is a reason for not running on the current stream.
This is just for cublas, cusparse and cudnn should be modified also.
