RFR: 8298083: The "CheckBox/RadioButton[Enabled/Disabled].textForeground" stoped working

[Sergey Bylokhov]

We have two types of properties in Swing, the "basics": were implemented a long time ago. Some of that properties are tested by the bug4314194 test. And other properties implemented as part of the Synth L&F, and based on it - Nimbus/GTK. Attempt to fix the issue reported by bug4314194 added support of two "basic" options to the Nimbus/GTK but at the same time broke the Synth/Nimbus properties. It is unclear what is the root cause and how these properties should work together(should they? I assume each "basic"/"synth" should support its own) I suggest to revert the changes in 20 to prevent the regression and rethink the solution later.

In short, this is a request to revert the next fixes:
 * https://bugs.openjdk.org/browse/JDK-8075916 - for some reason broke the Synth/Nimbus properties
 * https://bugs.openjdk.org/browse/JDK-8295006 - This uses the same approach as the fix above
The next two issues created to redo both:
 * https://bugs.openjdk.org/browse/JDK-8298149
 * https://bugs.openjdk.org/browse/JDK-8298153
