This disconnects ownership of the `File` reference in a compiler from
the calling scope, which is required for when we implement `import`.
`import` will need to carry an `Rc<RefCell<CodeMap>>` (or maybe, in
the future, Arc) to give us the ability to add new detected code
files at runtime.
Note that the choice of `Arc` over `Rc` here is not ours - it's the
codemap crate's.

Impl Arbitrary for Value (and NixAttrs and NixList) in the same way we
did for NixString. Value currently only generates non-"internal"
values (no thunks, AttrNotFound, etc.) and can't generate
functions (builtins or closures), because those'd require full
generation of tvix bytecode, which is a bit more work than I'd like to
do now - there's a `todo!` left in the code for a place where we could
allow opting-in to internal values and functions later.

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 trait can be used to convert most structures from rnix-parser

This will be used in the next commit to clean up the span handling in

Yep.
This is kind of ugly right now. The idea is that the recursive_scope
compilation function is used for recursive sets as well by emitting
the keys. The rest of the logic is pretty much identical.
There is quite a lot of code here that can be cleaned up (duplication
between attrs and let, duplication inside of the recursive scope
compilation function etc.), but I'd like to get it working first and
then make it nice.
Note that nested keys are *not* supported yet.

This makes the phases of attribute set construction that Nix has very
explicit (inherits, static keys, dynamic keys).
This change focuses on the split between dynamic/static keys by
collecting all dynamic ones while compiling the static ones, and then
phasing them in afterwards. It's possible we also need to do some
additional splitting inside of the inherits.

This function is necessary for all builtins that expect some form of
path as an argument. It is merely a wrapper around coerce_to_string that
can shortcut if we already have a path. The absolute path check is done
in the same way as in C++ Nix for compatibility, although it should
probably be revised in the long term (think about Windows, for example).
Since coercing to a path is not an operation possible in the language
directly, this function can live in the builtins module as the only
place it is required.

With this puzzle piece of string compilation in place, `compile_str`
becomes less redundant, as every part now needs to be compiled the same.
The thunking logic becomes a bit trickier, since we need to thunk even
in the case of `count == 1` if the single part is interpolating.
Splitting the inner (shared) code in a separate function turned out to
be easier for making rustc content.

If we have multiple string parts, we need to thunk assembling the
string. If we have a single literal, it is strict (like all literals),
but a single interpolation part may compile to a thunk, depending on how
the expression inside is compiled – we can avoid forcing to early here
compared to the previous behavior.
Note that this CL retains the bug that `"${x}"` is erroneously
translated to `x`, implying e.g. `"${12}" == 12`.
The use of `parts.len()` is unproblematic, since normalized_parts()
builds a `Vec` instead of returning an iterator.
