Lists are compared lexicographically in C++ nix as of [0], and our
updated nix test suites depend on this. This implements comparison of
list values in `Value::nix_cmp` using a very similar algorithm to what
C++ does - similarly to there, this requires passing in the VM so we can
force thunks in the list elements as we go.

Adding these to the C++ Nix CI ensures that it is possible for the
tests in that directory to pass at all. Mainly this would catch
situations like fixed in a previous CL when moving the tests around
would break them so that they wouldn't even pass in C++ Nix.
For this to work, we need to track skips by basename to be
directory-independent (assuming that every skipped test name is unique
is hopefully okay).

The language test suite actually doesn't require flakes and the
new features are mostly sensible (added builtins) as well as some
tests for regressions the C++ implementation experienced.
The path interpolation test is not included in this update because there
is no way to construct an location-independent .exp file for it (the C++
repo also doesn't have one). We may still want to implement that feature
eventually (in case rnix adds support for it).
The C++ Nix revision used is ac0fb38e8a5a25a84fa17704bd31b453211263eb.

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.
