SF: Connect the VDS scratch surface producer 

- VirtualDisplaySurface has a BufferQueue for producing scratch
  buffers when doing mixed composition for a virtual display.
- Connect/disconnect the producer end of this BufferQueue in the
  VirtualDisplaySurface constructor/destructor to avoid using it in a
  disconnected state.
