Signed-off-by: p-wysocki ### Description Add `LpPool-18`, which now has `ceil_mode` and `dilations` attributes. Deprecate `auto_pad`, like it is done in the case of [AveragePool](https://github.com/onnx/onnx/blob/main/docs/Operators.md#averagepool) and [MaxPool](https://github.com/onnx/onnx/blob/main/docs/Operators.md#maxpool). ### Motivation and Context...

Add Split-20 - change uneven split behavior to be more torch-like
