> since onnx requests same padding mode, we need to optimize conv and pooling these 2
operators.
> FYI:
> {quote}auto_pad must be either NOTSET, SAME_UPPER, SAME_LOWER or VALID. Where default
value is NOTSET, which means explicit padding is used. SAME_UPPER or SAME_LOWER mean pad the
input so that the output spatial size match the input.In case of odd number add the extra
padding at the end for SAME_UPPER and at the beginning for SAME_LOWER. VALID mean no padding.
> {quote}
> This JR will finish:
>  # conv and pooling support SAME_UPPER, SAME_LOWER for both forward and backward, 2d
and 1d.
>  # For SAME_UPPER, SAME_LOWER, can do shape checking, and if not set shape, can compute
the correct shape.
>  # Test cases.
