RFR: 8319340: [Linux] Disabled windows should not allow window operations (minimize, resize, maximize, close) [v2]

[Thiago Milczarek Sayao]

> JavaFX on Linux is allowing disabled windows to be minimized.
> 
> Currently close does nothing as it should, maximize disappears (on MS Windows it's greyed out - it's a platform behavior difference) and minimize is being allowed.
> 
> Thins PR removes WM functions when window is disabled and restores it back when it's re-enabled.
