Don't automatically handle context parameter (#16867)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/16867
Some caffe2 operators (example: BBoxTransform) have not just one template parameter which is the context, but might have multiple template parameters.
Because of this, we can't handle the context parameter inside the macro.
