6a4d55f2 - [ONNX] Enable onnx shape inference in export by default (#46629)

[ONNX] Enable onnx shape inference in export by default (#46629) Summary: * Enable ONNX shape inference by default. * ONNX could potentially set inferred shape in output instead of value_infos, checking both to be sure. * Small fix in symbol_map to avoid overlooking dup symbols. * Fix scalar_type_analysis to be consistent with PyTorch scalar type promotion logic. * Correctly handle None dim_param from ONNX inferred shape.
