EIP-7702: Set EOA account code [devnet-5 version]

[gumb0]

Depends on ethereum/evmc#720

Note: with the future change to EXTCODE* behavior, it will no longer be required to resolve delegation on the Host side, because Host::code_copy() will return full delegation designator and EVM could resolve it from that. So EVMC change could be simplified (not require Host::get_delegate_address())
