[NETCFGX][UUID] Add private interface used by WinXPs ifmon.dll

Browse Source 
When I loaded WinXPs ifmon.dll into our netsh.exe and ran the 'interface ip show address'
command ifmon tried to query an unknown interface. Google found a name for the GUID:
INetCfgComponentPrivate.
I implemented the three standard methods of the interface and ran some more tests.
After adding a 4th method with tree parameters to the interface, there are no more
failures.
