Help: Re-enable native WebKit help viewer

Browse Source 
Was disabled since QMacCocoaViewContainer is gone in Qt 6. Works with
the suggested QWindow::fromWinId + QWidget::createWindowContainer
though.

WebKit(1) is deprecated though, and litehtml works pretty well nowadays,
so this is more academical than really useful. (litehtml stays the
default, opt-in to WebKit is possible in Preferences > Help > Viewer
backend)
