The  jpackage tests take a significant amount of time on some platforms (on macOS and Windows in particular). The changes here remove tools/jpackage from core_tools (it's not a core tool anyway) and adds the tests to tier3. In the future then maybe tier3 can be split up if needed.

This PR looks fine.  Per our offline discussion, need to revisit the CI configurations to ensure these tests are covered.
