Add interface for controlling single buffer auto refresh

- Adds a boolean to BufferQueue that controls whether or not auto
  refresh is enabled in SurfaceFlinger when in single buffer mode.
- Adds plumbing up to ANativeWindow.
- When enabled, it will cache the shared buffer slot in Surface in
  order to prevent the Binder transaction with SurfaceFlinger.
