\brief Backend function to allocate temporal workspace.

\note The result allocated space is ensured to be aligned to kTempAllocaAlignment.

\param nbytes The size of the space requested. \param device_type The device type which the space will be allocated. \param device_id The device id which the space will be allocated. \param dtype_code_hint The type code of the array elements. Only used in certain backends such as OpenGL. \param dtype_bits_hint The type bits of the array elements. Only used in certain backends such as OpenGL. \return nullptr when error is thrown, a valid ptr if success
