* \brief The calculation of the Dequantize interface requires the developer to reserve or apply for temporary space.
* The relationship between the maximum temporary space (maxTmpBuffer) and the space occupied by the input (inputSize x
* typeSize) is as follows: maxTmpBuffer = maxLiveNodeCount * inputSize * typeSize + extraBuf
* This interface is used to obtain maxLiveNodeCount and extraBuf.
* \param [in] srcShape, input shape information
* \param [out] maxLiveNodeCount, the multiple of the maximum temporary space to the input occupied space
* \param [out] extraBuf, the size of the extra temporary space
