<i18n dev> RFR: 8276794: Change nested classes in java.desktop to static nested classes [v2]

[Andrey Turbanov]

> Non-static classes hold a link to their parent classes, which in many cases can be avoided.
> I updated only private and package-private classes. Didn't touch public/protected to not break external code.
> Similar cleanup in java.base - [JDK-8261880](https://bugs.openjdk.java.net/browse/JDK-8261880)
