Fix breakpad build + add test canary (#60990)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/60990
This makes the breakpad build more explicit in its messaging and hints to cmake where to look for the library (it wasn't able to find it without `PATHS` on CI even though that works locally). This also adds a smoke test that will fail if breakpad isn't present on a CI job where it is expected (e.g. binary builds).
