* \brief compute axpy dst = src * scalar + dst
* \tparam isReuseSource: Whether to reuse the buffer of srcTensor.
* If the value is true, srcTensor can used as tmpBuffer and the data in it will be overwritten.
* If the value is false, srcTensor will not be used as tmpBuffer for calculation.
* \param [out] dstTensor: output LocalTensor
* \param [in] srcTensor: input LocalTensor
* \param [in] scalarValue: input scalarValue
* \param [in] sharedTmpBuffer: extra temporary shared space used for intermediate values among calculation process,
* whose required space size should refer to corresponding tiling API, which is defined at axpy_tiling.h.
* Generally, the more space you allocate, the better performance you will achieve, and the performance
* reaches peak when buffer size is maximum(calculated by tiling function). Moreover, it is not guaranteed
* that the shared space will be cleared after usage, the data could be anything.
* \param [in] calCount: input total calCount
