<i18n dev> RFR: 8358170: Repurpose testCompat in test/jdk/java/util/TimeZone/Bug8167143.java

[Justin Lu]

Please review this PR which modifies the test/jdk/java/util/TimeZone/Bug8167143.java "testCompat" case to be repurposed to check the implicit locales for the FALLBACK BreakIterator and Collator providers. (FALLBACK is the primary provider in those cases.) Since the method is corrected, it can be re-added as a test case. This change stems from discussion in https://git.openjdk.org/jdk/pull/25532.
