Migrate Ant UI performance tests to JUnit 5

[HeikoKlare]

The performance tests in org.eclipse.ant.tests.ui still rely on the JUnit 3 PerformanceTestCase. In addition, one test class is missing in the according test suite.

• Migrates all Ant UI performance tests and test suites to JUnit 5
• Adds the missing OpenLaunchConfigurationDialogTest performance test to the performance test suite

SeparateVMTests as part of the performance test suite is not yet migrated to JUnit 5, as it is derived from an ordinary Ant UI test, which is still based on JUnit 3. This will be migrated once the other, ordinary Ant UI tests are migrated to JUnit 4 / 5.

Note that the performance tests are not executed in CI builds, so the change will probably not have any effect that is automatically validated.
