  Use EnumAdapters to properly detect primary GPU on Win
  
  EnumDisplayDevicesA returns the card that's connected to the display,
  but EnumAdapters return the adapter which the desktop primary is
  displayed at index 0. We can use this to determine the device used for
  graphics.
  
  Also cleans up the discrepancy between platforms on finding "primary" vs
  "active" GPU. Asserts that the GPU expected to run ANGLE commands is the
  active GPU, and deprecates the primary GPU to be equal to the active
  GPU.
