builtins.readFileType was added to Nix back in version 2.14.
The tests were also moved out of notyetpassing in addition to the
readDir fixtures they depend on.
I caught a bug where we previously used std::fs::metadata (via the
.metadata() method on File) which follows symlinks so it would always
return false for is_symlink(). Instead we now use
std::fs::symlink_metadata directly which does not follow symlinks, so
tests now pass. This wasn't an issue for builtins.readDir as it uses
walkdir and walkdir doesn't follow symlinks either.

The primary addition is the `builtin_hashFile` function which attempts
value-path coercion and on success reads the file to a nix_string.
Similar to the `builtins_hashString` implementation, the hash is then
derived using the `hash_nix_string` function in the introduced hash
module which has extracted hashing functionality initially specified in
cl/11005.

In case a .exp.xml file is provided alongside the test, compare its
output with the desired state.
Also, add some function .exp.xml that were presumably moved out of the
way back to src/tests/nix_tests, as they now produce the correct XML
output.

These need to be preserved at least for builtins.toXML.
Also, we incorrectly only wrote an <attrspat> in case ellipsis was true,
but that's not the case.

This relies on TEST_VAR=foo being set to "foo".
Nix does this in tests/functional/lang.sh, we do it in the test suite.

New test cases we don't pass:
- fromTOML timestamp capabilities
- path antiquotation
- replaceStrings is lazier on C++ Nix master

This drops the usage of serde::Serialize, as the trait can not be used
to implement the correct semantics (function colouring!).
Instead, a manual JSON serialisation function is written which
correctly handles toString, outPath and other similar weirdnesses.
Unexpectedly, the eval-okay-tojson test from the C++ Nix test suite
now passes, too.
This fixes an issue where serialising data structures containing
derivations to JSON would fail.

Introduces granular dependency builds using crate2nix, bootstrapped
off the generated configuration from the newly introduced
workspace (see cl/7533).
This commit checks in the generated Cargo.nix file which can be
regenerated with a parameterless invocation of `crate2nix generate` in
`//tvix`. I tried generating this in IFD, but it turned out to be
harder than what seemed worthwhile for now.
In this setup, the various build targets for Rust projects end up
being attributes of the imported `Cargo.nix` file at the `tvix.crates`
attribute. These still lack configuration, however, which has been
fixed in the various `default.nix` files of individual projects.
Note that we (temporarily) lose the ability to build tvix-eval's
benchmarks in CI. I haven't figured out what magic incantation summons
them from the void again ...
The `eval-okay-readDir` tests from both test suites have been disabled
because they fail for unknown reasons when run in this new derivation.
Somebody will have to debug it!

This function covers builtins.genericClosure, seemingly including
weird behaviour around the order in which the work set is processed.
For some reason, in C++ Nix the test expectation is written in XML
which we do not yet support, so I have created a new expectation file
using `nix-instantiate --eval --strict` on the file (yes, using C++
Nix).

The current implementation of nix_eq will force one level of thunks
and then switch to the (non-forcing) rust Eq::eq() method. This
gives incorrect results for lists-of-thunks.
This commit changes nix_eq() to be recursive.
A regression test (which fails prior to this commit) is included.
This fix also causes nix_tests/eval-okay-fromjson.nix to pass, so it
is moved out of notyetpassing.

This is a bit tricky because the comparator can throw errors, so we
need to propagate them out if they exist and try to avoid sorting
forever by returning a reasonable ordering in this case (as
short-circuiting is not available).

I played around a little bit with doing this in-place, but ended up
going with this perhaps slightly clone-heavy approach for now because
ideally most clones on Value are cheap - but later we should benchmark
alternate approaches that get to reuse allocations better if necessary
or possible.

This commit implements builtins.currentSystem, by capturing the
cargo environment variable `TARGET` and exposing it to rustc as
`TVIX_CURRENT_SYSTEM` so it can be inserted into the source code
using `env!()`.
The resulting value needs to be massaged a bit, since it is an "LLVM
triple". The current code should work for all the platforms for
which cppnix works (thanks qyliss for generating the list!). It
does *not* reject all of the triples that cppnix's configure.ac
rejects -- it is much more forgiving. We can tighten this up in a
future commit.

This is done via a new `deepForce` function on Value. Since values can
be cyclical (for example, see the test-case), we need to do some extra
work to avoid RefCell borrow errors if we ever hit a graph cycle:
While deep-forcing values, we keep a set of thunks that we have
already seen and avoid doing any work on the same thunk twice. The set
is encapsulated in a separate type to stop potentially invalid
pointers from leaking out.
Finally, since deep_force is conceptually similar to
`VM::force_for_output` (but more suited to usage in eval since it
doesn't clone the values) this removes the latter, replacing it with
the former.

eval-okay-eq.nix is actually an ancient test case that used the ATerm
syntax for the test result. It was disabled for a while, since the
behavior got reverted for a bit, but works on any reasonably modern
Nix implementation. This change matches my [C++ Nix PR].

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).

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.
