<AWT Dev> RFR: 8264125: Specification of Taskbar::getIconImage doesn't mention that the returned image might not be equal to the Taskbar::setIconImage one. (eg on Mac OS) [v2]

[Alexander Zvegintsev]

> This fix is to explicitly specify that `Taskbar::getIconImage` may return an object different from passed to `Taskbar::setIconImage`.
> 
> Actually it is always returns a different object on macOS(the only OS which supports this feature), but I want to save some options if we decide to rework this.
