RFR: 8265694: Investigate test StressHiddenClasses.java

[Harold Seigel]

Please review this trivial change to remove test test/hotspot/jtreg/runtime/HiddenClasses/StressHiddenClasses.java because, as pointed out in the review of JDK-8243287, this test is duplicated by test StressClassLoadingTest.java.

Thanks, Harold
