RFR: 8346753: Test javax/swing/JMenuItem/RightLeftOrientation/RightLeftOrientation.java fails on Windows Server 2025 x64 because the icons of RBMenuItem and CBMenuItem are not visible in Nimbus LookAndFeel

[Prasanta Sadhukhan]

Issue is RadioButtonMenuItem and CheckBoxMenuItem bullet/checkmark icon is not displayed in WindowsL&F when the test is run with NimbusL&F.
This is because `WindowsIconFactory#VistaMenuItemCheckIcon.paintIcon` called `getLaFIcon()` which returns a empty NimbusIcon which causes no icons to be drawn. This is because the test after setting WIndows L&F of the menuitem reverts back the Windows L&F to Nimbus L&F via `UIManager.setLookAndFeel(save);` call in the test so when frame is made visible, the L&F resets back to Nimbus L&F resulting in null NimbusIcon.

Fix is made to make sure the whole frame is updated to cater to L&F change via `SwingUtilities.updateComponentTreeUI(frame);` call and keep the L&F without reverting back to original L&F..
