Update window surface while activity is set to full screen.

Update window surface while activity is set to full screen.

Other than surface resized or surface moved, setSurfaceBoundariesLocked
in WindowStateAnimator.java may encounter another scenario that the
flag of window is set to LayoutParams.FLAG_FULLSCREEN. In all of
scenarios, updateSurfaceWindowCrop(...) should be called separately
to avoid float window flickering when it's dragged off screen.

This patch is meant to refine the previous patch:
