warn that initializers are in graph input provide a tool to move initializer out of graph input Motivation and Context ONNX model from IR_VERSION 4 only treats initializers that appear in graph input as non-constant. This may fail some of the graph optimizations, like const folding, operator fusion and etc. Warn the case and provide a tool.
