Abtin Keshavarzian 064529cbfc [nexus] add helper to allow link between nodes in nexus (#12906)
Added `Core::AllowLinkBetween()` and `Core::UnallowLinkBetween()`
helper methods to the Nexus test platform. These methods simplify
establishing bidirectional links between nodes in simulation tests by
handling the reciprocal `AllowList()` calls in a single step.

Updated various Nexus test cases to utilize these new helpers,
replacing manual bidirectional `AllowList()` calls. This change
reduces verbosity and ensures consistency in how links are established
in the test topology.
