[jdk25u-dev] RFR: 8346154: [XWayland] Some tests fail intermittently in the CI, but not locally

[Roland Mesde]

Backporting JDK-8346154: [XWayland] Some tests fail intermittently in the CI, but not locally.

This PR fixes intermittent test failures on XWayland by adding delays after setVisible() calls and refactoring tests that immediately checked window state, addressing timing differences where XWayland delivers ConfigureNotify events asynchronously compared to X11.

For parity with Oracle JDK.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/jdk/java/awt/Choice/PopupPosTest/PopupPosTest.java
make test TEST=test/jdk/java/awt/Focus/ClearLwQueueBreakTest/ClearLwQueueBreakTest.java
make test TEST=test/jdk/java/awt/Frame/FrameSetMinimumSizeTest.java
make test TEST=test/jdk/java/awt/KeyboardFocusmanager/TypeAhead/ButtonActionKeyTest/ButtonActionKeyTest.java
make test TEST=test/jdk/java/awt/LightweightComponent/LightWeightTabFocus/LightWeightTabFocus.java
make test TEST=test/jdk/java/awt/Modal/ToFront/DialogToFrontModeless1Test.java
