test(tvix/eval): Add the start of a nix oracle test suite r/4886
Add the start of a test suite that compares tvix eval results against nix, using the string repr of the value as the comparison. This shells out to a nix-instantiate binary, which is configurable as an environment variable, to eval - there's some extra machinery there to setup a new nix store as a tempdir to allow running this test inside the nix build for tvix-eval itself. Currently this has a macro that'll allow writing lots and lots of hardcoded tests, but going forward I'm also going to be looking into adding proptest-based generation of expressions to compare.
