This commit adds a new Nexus test `TestFedRxOnlyLinkEstablishment` to verify that a Full End Device (FED) successfully establishes rx-only links with all its neighboring routers in the network. The test forms a topology with a leader and 15 routers, then adds an FED child. It uses the `NeighborTable` callback to track the addition of routers to the FED's neighbor table and ensures that it eventually establishes links with all available neighboring routers.
