WinRT: Added networkinterface and hostinfo

While QHostInfo and QNetworkInterface are implemented,
socket implementation is just a stub for now. Having
stub implementation is preferable over not having them
at all is because most applications will not build, if
sockets are not available. Even though they do not
do anything useful yet, applications can be compiled
and run to get an idea how network will work on WinRT.
