resample2d: Validate that dimensions are valid unsigned longs

If explicit sizes aren't provided, the size of an output dimension is
calculated as shape[i] * scales[i] which could be larger than can be
represented as a dimension in MLOperandDescriptor.

Explicitly validate and throw if this constraint isn't satisfied.

Fixes webmachinelearning#610
