Use JavaCPP Preset for ONNX

[EmergentOrder]

The JavaCPP Preset for ONNX contains everything that you get from the implementation generated from the protobuf that is currently used. You also get the ability to "polish" and convert the version of a model (in this PR ) as well as access to the operator schemas, the ONNX IR, ONNX-ML (Classical Machine Learning extension), ONNXIFI and more.
