Enabling QtVirtualKeyboard should automatically add necessary style and layout.qml files and import statements in order to customize

It is very difficult to customize a virtual keyboard in Design studio because there is very little documentation on this already.  It would be much easier if the necessary "style.qml" and "layout.qml" files and their import statements into .qmlproject were auto-generated when "use qtVirtualKeyboard" is enabled in design studio.
