  Vulkan: Add support for AHB usage FRONT_BUFFER flag
  
  AHB usage flags have been updated to include front buffer usage.
  AHBs tagged with this flag need to be handled similar to single-buffered
  window surfaces especially w.r.t glFlush semantics. Account for the
  new usage flag when deferring flushes.
  
  Bug: angleproject:7956
  Test: Android VTS GraphicsFrontBufferTests.*
