Self-delegation Precompile use Staker as 20-length bytes address while contracts uses 32-length bytes address

In the AssociateOperatorWithStakerand DissociateOperatorFromStakerof delegation precompile contract, staker address is processed with evm address format, which is 20-length address.

  // TODO: In the future, the check should be the same as it is in delegation if using LayerZero to route the
  // message for non-EVM client chains, such as Solana.
  if len(staker) != common.AddressLength {
    return nil, fmt.Errorf(exocmn.ErrInvalidEVMAddr, staker)
  }

but in exocore-contracts, it uses the common 32-length address.
