[ONNX] Set the name of the producing node using the value name (pytorch#155413)

When comparing two graphs exported using different opset versions, even though the value names are the same in both graphs, the node names did not match, causing model-explorer to not be able to sync the two graphs. This change updates the names of the nodes that directly produce the output values, for better correspondence across exported graphs.
