Minor fixes to onnx to onnxscript converter

[gramalingam]

Minor fixes to onnx to onnxscript converter:

• Embed node name as a comment in generated onnxscript
• Handle sequence types (just for readable representation)
• Minor tweak to handling of initializers, distinguishing small and large tensors (when replacing them by random values)
• Handle INT8 type initializers, which show up in quantized models.
