Describe
Op developers may now write "no_need_buffer: X, Y" in Yaml file, so as to drop the underlying allocation for Tensor X and Tensor Y when creating TensorWrapper.
AutoCoden script will detect "no_need_buffer" field and set a special boolean when constructing TensorWrapper. In that scenario, TensorWrapper will only copy everything except for the underlying allocation from Tensor X or Tensor.
