core/evm: Random opcode (EIP-4399)

[MariusVanDerWijden]

This PR implements EIP-4399, the RANDOM opcode post-merge.
Since we don't know the merge block number beforehand, we need to somehow signal to the EVM that the Random opcode should be used now. For that I've implemented the SetVMConfig method. Since the transition can happen both during block insertion over the API and during the sync, I needed to add a lock for the vmConf. Might not be the greatest way to do it (suggestions very welcome). I also pass the vmConf by value now, not by reference as it is dereferenced in all callers anyway.

Additionally I extended the StateTestUtil to be able to create state tests with the RANDOM opcode. An example for that later.

replaces #23985
