  Vulkan: Add external's pNext to ANGLE_external_objects_flags
  
  ANGLE was chaining VkImageFormatListCreateInfoKHR to
  VkImageCreateInfo::pNext to support sRGB extensions.  For external
  images, it was unknown whether that was valid because there was no way
  to know if external used an identical chain of pNexts.  This was causing
  a discrepancy between images created by Chrome and those created by
  ANGLE as part of an import.
  
  This change updates ANGLE_external_objects_flags to take in the pNext
  chain external has used to create the image so ANGLE could create the
  image identically.
