RFR: 8316931: [macos14] Test "java/awt/TrayIcon/ShowAfterDisposeTest/ShowAfterDisposeTest.html" throws and exception on Mac OS 14(x64, aarch64) [v12]

[Alisen Chung]

> SunToolkit.java is trying to post an event on the TrayIcon appContext, but the TrayIcon was already removed by the test, causing an error. The fix is to make SunToolkit skip posting the event if appContext is null. The test is also updated to remove applet usage and use PassFailJFrame instead.
