feat(tvix/eval): implement correct toString behavior r/4857
Implement C++ Nix's `EvalState::coerceToString` minus some of the Path / store handling. This is currently only used for `toString` which does all possible coercions, but we've already prepared the weaker coercion variant which is e.g. used for builtins that expect string arguments. `EvalState::coerceToPath` is still missing for builtins that need a path, but it'll be easy to build on top of this.
