Fix compilation on Windows 10 (CUDA 10.0, Visual Studio 2017) (#19615)
Summary:
I want to use libtorch in a C++/CUDA project but as soon as I include `<torch/torch.h>`, ".cu" files fail to compile:
`torch/csrc/jit/script/tree.h(64): error C3520: 'args': parameter pack must be expanded in this context`
This PR makes it build on my machine (don't know if it breaks anything though).
