fix(tvix/eval): implement C++ Nix version part comparison algorithm r/4949
This is based on the [relevant code] in C++ Nix. Our version has more branches because the C++ one only checks if it is less than or not, so can save handling a few cases. We on the other hand, can avoid calling the algorithm twice. It'd be nice to implement proptests for this in the future and to make sure that this weird little algorithm doesn't violate the Ord laws.
