My guess is that MSVC C4530 needs to be disabled when building libgtest even
when we're not enabling exceptions for the same reason that I expected that
warning from our jfr/test_networkUtilization.cpp.

That jfr test includes `<vector>`, and vector::at throws, and that apparently
isn't protected by anything that knows about exceptions being disabled. (At
least, that's the problem I ran into a while ago.) So even if it's never
called, it still triggers the warning.

googletest also includes `<vector>` in a bunch of places, so I'd expect the same
issue there. Again, warnings even though that code is never called.
