SurfaceTexture: fix queues-to-composer

This change fixes the NATIVE_WINDOW_QUEUES_TO_WINDOW_COMPOSER query of
Surface and SurfaceTextureClient.  Surface now uses the inherited
SurfaceTextureClient implementation of this query.  SurfaceTextureClient
now queries SurfaceFlinger to determine whether buffers that are queued
to its ISurfaceTexture will be sent to SurfaceFlinger (as opposed to
some other process).
