This system is only actually touched by the game a tiny handful of times
during a round, yet it was the 4th top frametime consumer, because it
was querrying every potentially networkable entity in existence on the
maybe off-chance it was interacted with by a remote signaller. On a
typical station, this is tens of thousands of entities, with strong
linear scaling as the round time increases due to creation of new
entities.
I have tested this PR to verify that device links and signals still
work, except now with 99.99% less frametime cost.
