ENH: Add QuadBuffer stereo support

By default there is always an attempt to enable stereo capability. This is
done in ctkVTKAbstractViewPrivate::setupRendering [1].

Then, following the test done within the different implementation of
vtkRenderWindow, in case the hardware doesn't support it, the flag associated
with StereoCapability will be turned off [2][3].

Finally, the action within the threeD controller widget is enabled
or disabled based on the state of the StereoCapability flag.
