Use TestExecutionListener to log test start and end in org.eclipse.ui.tests

Add a JUnit Jupiter TestExecutionListener to org.eclipse.ui.tests,
which logs test start and end events via UIPlugin.
The listener is defined in org.eclipse.ui.tests.harness,
so that it can be reused by other test bundles.

Additionally, usage of TestRunLogUtil.LOG_TESTRUN rule is removed,
since the new listener covers the rule functionality.

Fixes: #4032
