Record external operation DelegationResolution

[manuelmauro]

Description

The current implementation of EIP-7702 is not properly recording delegation resolution as an external operation.

Is DelegationResolution even needed? Would emitting two times AddressCodeRead be flexible enough? I say this because on frontier this seems to be the case to me. Still having an explicit enum constant could be valuable.

I don't have preference. At this moment we can do what is better for Frontier. I think for other chains if they want to customize for more flexibility, some more hooks / code changes will be needed anyway than DelegationResolution.

Since on frontier having an external operation for DelegationResolution does not add complexity and makes the cost calculations more explicit I would slightly lean towards keeping it.

Reference commit on frontier.
