OCPBUGS-55649: Remove SetEIPForNLBIngressController feature gate

This change removes the Feature gate SetEIPForNLBIngressController from
the API.

The FG is not used anymore by cluster-ingress-operator and is not required
to be part of the code anymore.

Additionally, the FG has been enabled by default since 4.18 and can be safely
removed
