InferReactiveIdentifiers has some extra logic to find identifiers declared in the same scope, and promote non-reactive identifiers to reactive if they appear inside a reactive scope (reactive scope == scope with one or more (reactive) dependencies). Even though the identifier alone might not be technically reactive (have no reactive inputs), it can get re-recreated if the scope re-evaluates. We can now do this during PruneNonReactiveDependencies as we exit out of each scope.
