use c++17 when building windows smoke tests (#1365)

Summary:
We are seeing failures during CI dealing with some headers that have
nested namespaces. This is expected to remedy them.

One such example:
https://github.com/pytorch/pytorch/actions/runs/4510336715/jobs/7942660912

Test Plan: Test this with CI.
