Extract QGuiAction(Group) from QAction(Group) into QtGui

Simply moving QAction to QtGui was not deemed possible since
it operates on a set of controls of some kind. The approach to
extract a base class was taken instead, named QGuiAction
following the QGuiApplication scheme. QAction remains in
widgets, but changes base class.

For QActionGroup, the functions addAction(text/icon), which
create an action, cannot be implemented in QtGui, hence a base
class is needed, too (unless they are deprecated and removed).

- Extract base classes providing functionality not based on
  QtWidgets, using virtuals in QGuiActionPrivate to provide
  customization points

- Change QActionEvent to take QGuiAction, removing
  the need to forward declare QAction in QtGui

[ChangeLog][QtGui] Added QGuiAction(Group) and made the equivalent
existing classes in Qt Widgets derive from them. This provides
basic functionality for implementing actions in QML.
