8380223: Refactor test/jdk/sun/util/resources TestNG tests to JUnit

[gnu-andrew]

This backport updates the sun.util.resources tests to use JUnit. It eases the backporting of JDK-8381379: "Support std/dstOffset attributes in CLDR's metazone definitions" - itself a pre-requisite for the next tzdata update - which adds further tests in JUnit format to TimeZoneNamesTest.java. Other changes from the umbrella task (JDK-8307843) for these conversions are already in 25u such as JDK-8310049.

The backport was mostly clean, bar test/jdk/sun/util/resources/TimeZone/Bug8139107.java, which was altered by JDK-8260555: "Change the default TIMEOUT_FACTOR from 4 to 1". I applied the copyright header change and testng -> junit substitution manually, without the timeout in the latter from 8260555.

All tests pass:

$ make -C $HOME/builder/25u-dev run-test TEST="jdk/sun/util/resources"
