Make Onnx resize ALWAYS parse to a Resize op

[bpickrel]

Low priority enhancement to Issue 1670:

make_gather_instruction() function calls in parse_resize.cpp can be replaced by invoking the Resize op. as follows: /* TODO: to make Onnx resize ALWAYS parse to a Resize op, replace the above line with the following. But it will break a lot of onnx tests. Note that this can only be done if a compiler pass is made to convert to the gather version from the Resize op. Additionally the current Resize op will need to handle all the needed cases.

                   ***  Call resize with only one argument and static scales or sizes
                   attribute.
            */
             Default "mode" attribute is "nearest"
            if(scales_sizes_arg->get_shape().type()  == shape::int64_type )
            {
                return info.add_instruction(make_op("resize", { {"nearest_mode",
                nearest_mode}
                    , {"coordinate_transformation_mode", coord_trans_mode}, {"sizes",
                    in_lens}}), args[0]);
            }
            else
            {
                return info.add_instruction(make_op("resize", { {"nearest_mode",
                nearest_mode}
                    , {"coordinate_transformation_mode", coord_trans_mode}, {"scales",
                    vec_scale}}), args[0]);
            }
