NetworkStateNotifier on Mac reports IPv6-only networks as offline
https://bugs.webkit.org/show_bug.cgi?id=316409
Reviewed by Basuke Suzuki.
NetworkStateNotifierMac only consulted the IPv4 SCDynamicStore entity
when probing each network interface, so machines on IPv6-only links
(e.g. NAT64 / cellular IPv6 PD / IPv6-only Wi-Fi) walked every
interface, never found an IPv4 entity, and reported the system as
offline. As a result, navigator.onLine was false even though the
network was fully reachable.
The notification key list had the same asymmetry: only the IPv4
global entity and an IPv4 per-interface pattern were watched, so
IPv6-only state changes did not wake the notifier.
Also probe kSCEntNetIPv6 per interface, and add the IPv6 global
entity plus an IPv6 per-interface pattern to the watched keys.
