To facilitate backporting, this PR may be broken into two PRs: the first one which updates the API of `PassFailJFrame`, the second, dependent, PR updates the tests.

I faced some difficulties when I was backporting `PassFailJFrame` to 17u and 11u because some changes to the framework were combined with tests. The `PrintLatinCJKTest` test that is modified here isn't backported to 17u or 11u.

I will definitely want to backport these changes to previous versions of JDK, so I am for *splitting the PR*. Thank you, @DamonGuy, for bringing this up.
