Please review this PR which removes the i18n related testing base classes `IntlTest` and `CollatorTest` and converts all the tests that use them,
IntlTest and CollatorTest are testing classes which are extended by tests in `text/`, `util/Locale`, `util/TimeZone`, and `util/Calendar`. The abstract testing classes are quite dated and have caused issues such as: variation between OS, hiding stack trace, and causing tests to spuriously pass. This change mainly automates a low level conversion of all the tests (75) using the frameworks; all tests were converted to use JUnit instead. (With the exception of `DateFormatRoundTripTest` due to the nature of the test).
