Primarily on the request of Ipsilon to ease reviving the EOF branch.
(in case anybody wonders: it's not an issue that it's not even clear what will actually be in Prague - this is just the version switch and Prague will anyways be backwards compatible - and there's precedent for adding EVM version options in advance - so we can just add this without further thought and then gradually build up features as they materialize, while Ipsilon can make use of it in their EOF branch)
Introduce prague as EVM version (without yet implementing any features for it). Can be modelled after https://github.com/ethereum/solidity/pull/14705.
