kcmkwin/kwintabbox: Remove API not supported by KWin core
WindowThumbnailItem in scripting doesn't support any of the 'brightness', 'saturation', 'clipTo' anymore, so it makes no sense to support it in the KCM's preview.
See deprecation notes in https://invent.kde.org/plasma/kwin/-/blob/master/src/scripting/windowthumbnailitem.h#L30
Previews still appear to render fine, aspect ratio and all. Sorry @vkrause
sourceSize
seems not taken into account but that appears to be a pre-existing bug, it never used it anywhere before either.
