refactor(tvix/eval): use im::Vector for NixList representation r/5534
This is a persistent, structurally sharing data structure which is more efficient in some of our use-cases. I have verified the efficiency improvement using `hyperfine` repeatedly over expressions on nixpkgs. Lists are not the most performance-critical structure in Nix (that would be attribute sets), but we can already see a small (~5-10%) improvement. Note that there are a handful of cases where we still go via `Vec` that need to be fixed, most notable for `builtins.sort` which can not currently be implemented directly using `im::Vector` because of a restrictive type bound.
