Reimplement the test discovery of the lang tests script in Nix which
allows for a more flexible skipping logic that can e.g. react to the C++
Nix version used. This allows us to run the test suite against both
C++ Nix 2.3 and the latest C++ Nix version 2.11. The latter is mainly
useful, so we can implement newer Nix features and still verify them
against the C++ implementation.

It is helpful to be able to use the test suite as a regression test:
make a change to the compiler/vm, re-run the tests, and if there are
any failures you know it's your fault.
Right now we can't do that, because the expected-to-fail tests are
mixed in with the expected-to-pass tests. So we can't use them as a
regression test.

Using `serde_json` for parsing JSON here, plus an `impl FromJSON for
Value`. The latter is primarily to stay "dependency light" for now -
likely going with an actual serde `Deserialize` impl in the future is
going to be way better as it allows saving significantly on intermediary
allocations.

Add a new derivation target to the passthru of tvix.eval that builds the
benchmark binaries, *and* copies them to the outupts of the derivation
via the (somewhat arcane) `copyBinsFilter` jq script arg to naersk. This
is a bit annoying because (as far as I can tell) the derivations
returned by naersk aren't directly overridable, so we have to explicitly
fixpoint the attrs we're passing.
Also, since this is now a separate target to build the benchmarks, we
can remove `--all-targets` from the build of `tvix-eval` itself since
that was only added to build benchmarks in CI, and make
regular (non-benchmark) builds a bit faster.

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.

This avoids unnecessary rebuilds of //tvix/eval when working on it
locally using impure cargo.
