### Description This removes the invocation of `convert_endian()` from `numpy_helper.to_array()` in favor of another implementation, since convert_endian() modifies the TensorProto. ### Motivation and Context This change was needed due to observed issues when trying to load an ONNX model that was exported on a s390x system via tf2onnx. Debugging showed that the TeensorProto was being modified by endianness conversion operations, which led to model incorrectness under certain circumstances. Fixes onnx#5901.
