* @brief Class representing Tensor for ACL
* @todo Override is_dynamic() method. We don't support dynamic tensor for ACL yet as of Apr, 2020.
* FYI, ACL ITensorInfo has is_dynamic() method, which seems currently not used.
* Maybe for ACL, this method can be implemented using ITensorInfo::is_dynamic() in future.
