[vcpkg] Remove the tombstones and 'ignore' baseline concepts. (#12197)
This changes our PR builds to treat 'fail' in the ci.baseline.txt as 'skip' instead of using tombstones.

We currently have large numbers of spurious failures that get enshrined in PRs through no fault of a PR author, removing the tombstones concept will fix those by allowing the user to retry. This does mean we accept some risk of not detecting when a port is 'fixed', but that failure is reasonable for us to handle after we see it in CI, but that seems worth it given that it lets us get rid of the tombstone concept.

This also helps out the binary caching feature, because we don't have to figure out how to productize tombstones.
