2. Bug 1607352 - Support DirectComposition virtual surface API. r=sotaro …

   Adds an #ifdef to the DCLayerTree implementation that allows
   selecting whether to use the virtual surface API (enabled by
   default) or the regular DC surface API.
   
   For now, this is a compile-time switch. As a follow up to this,
   we will support both options at runtime (for example, using the
   regular surface API for surfaces that have holes or translucency).
