…vailable methods return the correct info This change makes sure some of the IPGlobalProperties stop throwing exceptions and return the correct values. - GetIPv4GlobalStatistics, GetIcmpV4Statistics, GetTcpIPv4Statistics, GetUdpIPv4Statistics no longer throw NetworkInformationException. - GetActiveTcpConnections no longer returns TcpConnectionInformation instances only with the State of Unknown. - GetActiveTcpListeners return the correct IPEndPoint details for the IPV6 loopback. - NetworkInterface.GetIsNetworkAvailable no longer returns false for every call. The reason these methods were behaving incorrectly on iOS is due to Apple not including the public headers for icmp_var.h, ip_var.h, tcp_fsm.h, if_media.h, and udp_var.h in the iOS SDK. This would lead to, for example, pal_tcpstate.c always returning TcpState_Unknown even if the underlying native value was TCPS_ESTABLISHED. This change includes the missing public headers in our build. Fixes #36890
