  SystemInfo: Find primary with EnumDisplayDevices
  
  Without DXGI, EnumDisplayDevices is the only way to get the
  primary device. Previously the code would work on most configs
  with a combination of AMD, Intel and NVIDIA GPUs but would fail
  on more esoteric system. Like our try bots that have Matrox GPUs.
