fix: verify rootDir and all roots are directories

[SimenB]

Summary

See #9549 for background.

This could be considered a breaking change and I can print a warning instead?. Also, as mentioned in #9549, should we verify that roots exist in jest-haste-map as well? Not sure how that affects Metro, but jest-haste-map is super inconsistent in how it handles missing roots depending on whether Watchman is used and if the OS is Windows.

Closes #9549.

Test plan

Integration tests added

printing a warning instead of these 3 throws is trivial if we don't want a breaking change. However, I think non-existent directories provided to these options are so blatantly a configuration error that I think it's fine to throw

This makes sense to me, roots should always exist and failing is a good default.

bah, here we go https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/

these tests didn't pass for me at all, not just the symlink error 🤷‍♂ And the test error was just wrong path in the error message, otherwise it was correct
