For tests: creates all input and output tensors for this operator.
When running a network, all tensor shapes are specified in the network topology proto, and the network builder will automatically create them for you. In unit tests, this is a convenience method to avoid needing to create TensorShape protos.
This should only be called once the Operator is fully initialized with all required parameters. It is responsible for creating only the tensors it "owns". All operators "own" their output tensors, but not necessarily all of their input tensors. For example, a convolution operator "owns" its weight tensors, but not the input activations (which are the output of a previous Operator).
Note that "ownership" of a Tensor does not mean the Operator holds a std::unique_ptr to the Tensor; it simply means it is solely responsible for constructing and allocating memory for it.
