cf78d015 - remove use of ai.onnx.ml in test for custom ops and local functions (#19043)

remove use of ai.onnx.ml in test for custom ops and local functions (#19043) ### Description QNN_Nuget_Windows does not allow ai.onnx.ml operators but the test test_custom_op_local_function is using LabelEncoder. The operator can be removed as the test is only checking custom ops api. ### Motivation and Context Fix test test_custom_op_local_function in QNN_Nuget_Windows pipeline.
