  Don't use CGL in Mac Catalyst on Apple Silicon
  
  This change was made downstream in WebKit:
  https://bugs.webkit.org/show_bug.cgi?id=218303
  
  It turns out we must use EAGL in macCatalyst on Apple Silicon in all
  cases, not just in-process in iOS apps (the problem is not just about
  coexistence of the two GLs, but actually about our ability to load
  the accelerated renderer /at all/ in macCatalyst processes).
  
  I left the runtime switching in place, because there is a future in
  which we /can/ use CGL in non-iOS-app processes, but that future is
  not now.
