Creates a stream. Stream configurations can be added during stream creation.

This API must be used together with other APIs to create a stream. The API call sequence is as follows:

Call aclrtCreateStreamConfigHandle to create a stream configuration object.
Call aclrtSetStreamConfigOpt multiple times to set the value of each attribute in the configuration object.
Call aclrtCreateStreamV2 to create a stream.
After the stream is used, call aclrtDestroyStreamConfigHandle to destroy the stream configuration object and call aclrtDestroyStream to destroy the stream.

aclError aclrtCreateStreamV2(aclrtStream *stream, const aclrtStreamConfigHandle *handle)
