[jdk21u] RFR: 8311160: [macOS, Accessibility] VoiceOver: No announcements on JRadioButtonMenuItem and JCheckBoxMenuItem

Wed Aug 9 06:07:45 UTC 2023

This is backport of https://bugs.openjdk.org/browse/JDK-8311160 to jdk21u.

VoiceOver doesn't announce anything for JRadioButtonMenuItem and JCheckBoxMenuItem when navigated with down arrow key. JRadioButtonMenuItem and JCheckBoxMenuItem are having an accessible role of RadioButton and CheckBox respectively and it is required to notify native side whenever they are selected.

Added the required fix and tested with SwingSet2 application. CI testing is also fine.

Fix can be tested with SwingSet2 application and test instructions are mentioned in [JDK-8311160](https://bugs.openjdk.org/browse/JDK-8311160) description.
