[jdk17u] RFR: 8348760: RadioButton is not shown if JRadioButtonMenuItem is rendered with ImageIcon in WindowsLookAndFeel

Tue Sep 2 20:33:44 UTC 2025

I backport this for parity with 17.0.17-oracle based on the push to 21.

Resolved two copyrights and imports in SwingUtilities3.java.
Had to add another import to make it compile.
