Delete tests in org.eclipse.core.tests.resources eclipse-platform#525

In this commit, the deactivated performance tests "_testPerformanceManyResources()"  and "_testPerformanceOneResource()" from MarkerTest.java in org.eclipse.core.tests.resources are deleted because they are not real test methods but rather used for code measuring and printing the time for processing operations on markers. See also eclipse-platform#605 (comment). Contributes to eclipse-platform#525
