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.
