SurfaceFlinger: add a crop to the layer state
This change adds a crop rectangle specified in window coordinates to the layer
state. The all window pixels outside this crop rectangle are treated as though
they were fully transparent. This change also adds the plumbing necessary for
WindowManager to set that crop.
