796ddeb2 - Remove serialization of outer scope value info in ORT format model (#5077)

Remove serialization of outer scope value info in ORT format model (#5077) * Remove serialization of outer scope node arg info in ORT format model. We don't currently need it in a minimal build as only SessionState calls Graph::IsConstantInitializer and it doesn't search outer scope. If we do need it in the future the information can be calculated at runtime (small binary size cost to do so). Motivation: ORT format model was 32% bigger for a BERT model with multiple levels of subgraph and a lot of nodes due to this. Size is about 5% larger of the original ONNX model with the change. ORT format has type/shape info for all nodes, and this model has 2000 nodes so this seems reasonable. Added example code to dump ORT format model to json. Fixed misc bug in python test script around handling float and non-float expected output.
