Evm refactor (rebased on master a4c379a, 2022-06-13)

[holgerd77]

Rebased version and potential replacement for #1950

Rebase was a bit more hairy than expected 😋. 17 tests failing (VM -> API), most seem to be easy fixes (some base object not present, some EVM result not available "as is".

Nevertheless did not directly force-pushed on the original branch, but I would assume that it's worth to take this over here, fix the tests and then continue from here.

Rebased this after a local test rebase, also did a backup of the branch state before the rebase.

Will push soon afterwards with a VM api test fix.

Will leave some generic TODOs here, absolutely don't need to be answered right now.

• We shouldn't just double on the supported EIPs in EVM and VM and instead have a closer look which EIP belongs to what entity (my guess would be that the very most EIPs just only belong to EVM)
• Blockchain and optimally Block dependencies should be removed from EVM
• I am not really sure if I am getting for 100% why Interpreter is encapsulating so much EEI/state accessing logic (again?) but it looks clean and I guess I might be ok with it 😋

Ok, I will actually merge this in here so that we can proceed.

This still need an in-depth after-merge review, but then we can go on and e.g. do the package separation. Review work can be done in separate PRs.

Uff. No way back anyhow. 😜 😅 🥳

Looks good.

Still needs an in-depth post-merge review.

Will merge by admin-merge for procedural reasons.
