Add build option to disable C++ exceptions

[a-day-old-bagel]

I was able to get zphysics building together with zgpu on Windows again by disabling C++ exceptions.

If we can merge this, we might be able to turn on those two samples that stopped working in Windows.

Since I'm used to the old monorepo, this is a bit confusing, but I surmise that if we merge this, the next step would be to update the monorepo to point to the new commit here, and then, at that point, update monolith and physics_test_wgpu to turn on this no_exceptions option.

I believe this is enough to resolve the duplicate definition issue, since it has appeared to fix it for my own project. However, it might be necessary to also disable exceptions for other 3rd party C++ libraries too in some cases.

So once this is merged, I can fix those and make a PR on the monorepo too if you'd like.
