[NETCFGX][REACTOS][UUID] Uncover one of many secrets of netcfgx.dll

The second parameter of the first function of the INetCfgComponentPrivate interface seems to be a REFIID.
Netsh calls this function with an undocumented GUID called ITcpipProperties (see https://github.com/nihilus/GUID-Finder/blob/master/GUID-Finder/Interfaces.txt).
