RFR: 8341037: Use standard layouts in DefaultFrameIconTest.java and MenuCrash.java

[Alexey Ivanov]

Now that standard window layouts are available as part of the `PassFailJFrame` framework, we can use them in tests.

Two tests from #21180, specifically `test/jdk/java/awt/Frame/DefaultFrameIconTest.java` and `test/jdk/java/awt/Frame/MenuCrash.java`, use two test windows. At this time, the tests implement positioning explicitly in the test. After #21207 is integrated, these two tests could be updated to use the standard layout. They would serve as sample usage of multi-window test UI.
