[Roland Mesde]

Backporting JDK-8373716: Refactor further java/util tests from TestNG to JUnit.

This PR converts 14 java/util test files from TestNG to JUnit across Calendar, TimeZone, Properties, and ResourceBundle packages.

For parity with Oracle JDK.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/jdk/java/util/Calendar
make test TEST=test/jdk/java/util/Properties
make test TEST=test/jdk/java/util/ResourceBundle/modules
make test TEST=test/jdk/java/util/TimeZone
