C++ API: run shape inference as nodes are constructed

Here's an example of the new generated code:

AddN::AddN(const ::tensorflow::Scope& scope, ::tensorflow::InputList inputs) {
  if (!scope.ok()) return;
  auto _inputs = ::tensorflow::ops::AsNodeOutList(scope, inputs);
  if (!scope.ok()) return;
  ::tensorflow::Node* ret;
  const auto unique_name = scope.GetUniqueNameForOp("AddN");
  auto builder = ::tensorflow::NodeBuilder(unique_name, "AddN")
                     .Input(_inputs)
  ;
  scope.UpdateBuilder(&builder);
  scope.UpdateStatus(builder.Finalize(scope.graph(), &ret));
  if (!scope.ok()) return;
  scope.UpdateStatus(scope.DoShapeInference(ret));
  this->sum = Output(ret, 0);
}

Enabling shape inference unfortunately broke many tests. I fixed some of them, but for others I introduced a Scope::DisabledShapeInferenceScope() static method that returns a scope that doesn't perform shape inference. Eventually we should fix the tests that use this and remove it.
