Pull Request Overview

This PR adds stream parameters to the allocation and free functions in various CUDA sparse matrix operations to support asynchronous execution.

• Updated allocation calls in MatVecCUSPARSEHandle_t, MatMulCUSPARSEHandle_t, Sparse2DenseHandle_t, and Dense2SparseHandle_t to pass a stream.
• Updated free calls in the same classes to use the stream from params_.stream, aligning resource management with the new stream support.

• Ensure that the 'stream' passed to matxAlloc is consistent with the stream used in matxFree (params_.stream). Consider using a unified stream reference for clarity.

                stream);

include/matx/transforms/matmul/matmul_cusparse.h:159

• Verify that the stream used in allocation ('stream') matches the stream retrieved via params_.stream in the free call to maintain consistency.

                stream);

include/matx/transforms/convert/sparse2dense_cusparse.h:127

• Ensure that the 'stream' provided to matxAlloc is the same underlying stream used later in matxFree to avoid potential mismatches.

                stream);

include/matx/transforms/convert/dense2sparse_cusparse.h:136

• Confirm that the 'stream' passed during allocation is correctly aligned with the stream used in the free call (params_.stream), ensuring consistent resource management.

                stream);

include/matx/transforms/convert/dense2sparse_cusparse.h:182

• Verify that params_.stream is intended to be used here and is consistent with the stream passed in the allocation call to avoid mismatches.

      matxFree(workspace_, params_.stream);
