This adds a new ParcelSurfaceTexture.java class that can be instantiated with a SurfaceTexture and used to send the corresponding ISurfaceTexture interface to another process via Binder. The ParcelSurfaceTexture java object can then be used to create an ANativeWindow based on the SurfaceTextureClient interface. Change-Id: Ie38ea948b866e52f36a6d0f6cde19b54a8546817
