This PR is on top of #19735 (and is actually quite small). It adds support for EIP 1884, and makes use of the simplified chain management from #19735. It makes it possible to run statetests with e.g. Constantinople+1884, and thus apply 1884 without having Istanbul defined.

This PR creates core/vm/eips.go where any minor new eips can be added. Minor == eips that only

  • Add or remove opcodes, or
  • redefine opcode costs

For more invasive EIPs, that would modify the block validation or execution engine outside of the evm (e.g. progpow), this refactoring won't help much.

Rebased, squashed.
Due to some convoluted logic, the ExtraEips section was added to the vm.Config, since that's something that gets passed down into the function that eventually creates the vm.

This does add (a small) overhead, but that would be easily fixed if we reuse vm across all txs in a block.

My rebase happened to drop a commit where I moved SELFBALANCE to be according to EIP updates, and also repriced EXTCODEHASH. Now added back again.
