Implement geometryChangeRequested signal in the Quick API

Chromium includes the size of the frame in the requested geometry,
but QWindow::setGeometry() and the related properties of QML Window
expect a size without frame. This patch
 - fixes the geometry handling in Demobrowser example.
 - implements a new signal in the QML API which sends both frameless
and extended geometries to the application, because QML doesn't have
capability to determine the size of the frame and handle extended
geometry correctly.
