kt_jvm_test is incompatible with Java >= 18

[josephglanville]

Because of deprecation of the Security Manager APIs becoming an error in Java 18 kt_jvm_test will fail with the following error:

java.lang.UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release
	at java.base/java.lang.System.setSecurityManager(System.java:429)
	at com.google.testing.junit.runner.junit4.JUnit4Runner.installSecurityManager(JUnit4Runner.java:256)
	at com.google.testing.junit.runner.junit4.JUnit4Runner.run(JUnit4Runner.java:113)
	at com.google.testing.junit.runner.BazelTestRunner.runTestsInSuite(BazelTestRunner.java:145)
	at com.google.testing.junit.runner.BazelTestRunner.main(BazelTestRunner.java:76)

This can be worked around by specifying the appropriate JVM flags in .bazelrc:

common --jvmopt=-Djava.security.manager=allow

The correct fix however would be to port across the change made to the upstream Java test rule and read the runtime version from JavaRuntimeInfo and conditionally set the appropriate JVM option, see the Bazel issue for more details including the linked fix commit: bazelbuild/bazel#16421

Need to update to junit5 as the default.
