Farlight 84 now depends on GetIpInterfaceEntry (and Icmp6ParseReplies) presence (as originally discovered by Etaash Mathamsetty here: https://github.com/ValveSoftware/Proton/issues/6717#issuecomment-3168585829).
While isn't so far spotted using these functions it checks its presence and apparently some part of the SDK's component initialization is skipped if those are absent.
While empty stubs might be enough in this specific case it probably won't hurt to implement that properly. This MR concerns GetIpInterfaceEntry (while I am likely going to also look at iphlpapi Icmp6 ping implementation).
