  EGL: Remove egl::Error from validation code.
  
  Instead of using an egl::Error return value, errors are recorded
  on the egl::Thread immediately at the call site. This makes the
  code work the same way as in the GL entry points.
  
  Updates the EGL "try" macros to include a special handler for the
  EGL validation entry points. Uses a special ValidationContext
  helper class to preserve the existing info.
