  Implement missing util/ functions on Mac
  
  SetLowPriorityProcess's implementation can be shared between Mac and
  Linux so even though it isn't using a Posix API, it lives in the posix
  file.
  CreateOSPixmap needed to be implemented but will never be used by dEQP
  as our Mac EGL backend doesn't expose configs supporting pixmaps.
  
  Reland with a Linux compilation fix (forgot to delete
  SetLowPriorityProcess).
