Add a method to query the scene graph backend
Since 5.8, it has been possible to set the scene graph backend using
QQuickWindow::setSceneGraphBackend instead of using the environment
variables.
This caused some trouble with modules that need to know which backend
is used and relied on the environment variables or command line options
for getting this information. One example of such a module is
Qt WebEngine, which crashed because it ended up trying to use OpenGL
resources with the Qt Quick scenegraph software backend.
