  Re-land eglGetSyncValuesCHROMIUM extension.
  
  This reverts commit 20c97cac2a15144b61ceec7404a9e6249c40f50a
  and adds a few trivial changes to make it build with the current version
  of ANGLE code.
  
  Please see https://bugs.chromium.org/p/chromium/issues/detail?id=614147
  for more details on how this extension will be used.
  
  Original description:
  
  This change adds implementation of eglGetSyncValuesCHROMIUM extension
  on D3D11 with Direct Composition. This should work on Windows 8.1 and
  above.
  
  The implementation is based on IDXGISwapChain::GetFrameStatistics.
