// Calculates zero-point offset by reducing the weight and multiply it with zp.
// Originally, we have:
//   output = (int8_input - input_zp) * (int8_weight - weight_zp)
// So, offset = input_zp * int8_weight + weight_zp * int8_input
// - input_zp * weight_zp.
// This function calculates the `offset` value mentioned above. Note that the
