Revert "[dart:io] Concurrently resolve IPv4 and IPv6 addresses on iOS."

This reverts commit d7483c330c6d6eddced5d59b2ac2d1fd08352321.

Reason for revert: This CL causes a regression, we seem to be getting an uncaught exception when the application is offline. This later leads to problems when the application resumes after a wifi reconnect.

Original change's description:
> [dart:io] Concurrently resolve IPv4 and IPv6 addresses on iOS.
> 
> Original issue: On iOS, The problem is that people on iOS can have their
> IPv6 misconfigured so it doesn't work, but it's still turned on.
> Additionally getaddrinfo on that platform doesn't handle that case well,
> meaning that the IPv6 lookup takes a long time to time out, delaying the
> legitimate response.
> 
> This fix will issue a concurrent lookup for IPv4 and IPv6 on iOS.
> Whichever IP comes first will be used to try to build the connection.
>
