As followup of #9016 , we should address this comment i.e. remove from Westend Runtime VoterList, EPM, Staking as well.
This has a kind of domino effect. For example benchmarking of pallet_offences and polkadot_runtime_parachains::disputes::slashing needs to be heavily reworked since they are depending on staking pallet but they should depend instead only from StakingAhClient.
