Split all hardforks into EIPs

[jochem-brouwer]

Older hardforks currently have all EIPs "baked in": at VM level we do checks if common is currently at that hardfork or at a later hardfork (gteHardfork) and then execute logic.

It is cleaner to instead re-write all this logic as EIP-based logic. Then we check if the EIP is activated and execute the logic. At common, this means that older hardforks like Byzantium / SpuriousDragon etc. now have an EIP list of activated ones.

I would tend to not do this since ressources in the team are constrained and benefit/cost relation seems not strong enough to justify the effort.

I will close this for the feeling that this is too much work for not enough benefit, since disabling old EIPs which are already well-established has little use cases and for the newer EIPs we now have this in place for some time now.

Feel free to re-open if the need rearises.
