The root change is Ubuntu 22.04 bump, but that one could not be tested alone, because GHA would be broken due to missing compilers, dependencies, etc. Therefore, I opted to do a bulk PR that contains a series of inter-dependent changes. This PR should bring 17u GHA to the good state, atomically.

There are differences against JDK 22 GHA, but those look minor, not breaking/fixing current GHA, and we can backport separately once we get JDK 17u GHA in shape.

@RealCLanger, @TheRealMDoerr -- this approach makes sense to you? If so, I'll mark this PR ready for review. It would add the PR links to all affected issues, which I don't want to do unless we are going forward with this PR.
