WebView: Fix handling of key events

Browse Source 
Unhandled key events are sent to parent of QWebEngineView.
Hack with event filter on RenderWidgetHostViewQtDelegateWidget no longer
works for key events, so we need to install event filter on view
parent and handle key events there.
Downside is, that we can now only handle events that are not handled by
page itself.
