Adding `import` to builtins causes causes a bootstrap cycle because
the `import` builtin needs to be initialised with the set of globals
before being inserted into the globals, which also must contain
itself.
To break out of the cycle this hack wraps the builtins passed to the
compiler in an `Rc` (probably sensible anyways, as they will end up
getting cloned a bunch), containing a RefCell which gives us mutable
access to the builtins.
This opens up a potentially dangerous footgun in which we could mutate
the builtins at runtime leading to different compiler invocations
seeing different builtins, so it'd be nice to have some kind of
"finalised" status for them or some such, but I'm not sure how to
represent that atm.

This adds an initial working version of builtins.import which
encapsulates the entire functionality of `import` within the builtin
itself, without requiring any changes in the compiler or VM.
The key insight that enables this is that we can simply return a Thunk
from `import` that is constructed from the output of running the
compiler and - ta-da! - no other component needs to know about it.
A couple of notes:
* builtins.import needs to capture variables like the SourceCode
structure. This means it can not currently be constructed the same
way as other builtins and has special handling, which leaks out to
`eval.rs`. I have postponed dealing with that until we have this
working a bit more.
* the `globals` are not yet passed through
* the error representation for the new variants is absolutely not done
yet, we probably want to switch to something that supports
cause-chaining now (like miette)
* there is no mechanism for emitting warnings at runtime; we need to
add that

For some upcoming builtins (notably, import) we need to capture
arguments in the builtin's implementation.
To allow this, we can no longer use function pointers for builtins,
but must use a reference-counted closure object instead.
Unfortunately this adds an extra pointer operation to every builtin
call. We should benchmark this later against having a split builtin
representation.

The convention has changed to use `final` instead of `self` and `prev`

This change is notable in the Nixpkgs project code. I added a note
mentioning that the official documentation hasn't been update with

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.

We found a bug after updating to latest tvl-kit which broke

Bug was related to the fact that extra steps skip attribute had
precedence over parent configuration. This is a desired behavior when
extra step is explicitly set to `skip=true` but otherwise it must
follow parent.
Due to extra step normalization skip parameter is always set to false
if not explicitly set.
Along the way, I'm adding support for setting skip attribute on extra
steps as string so that people can define skip reasons.

This finishes up the implementation of nested keys after the key
insight that the nesting level does not need to be tracked, and
instead the attribute iterator can simply be retained inside the
structures as is (in an advanced state).
With this implementation, when encountering a nested key, the Tvix
compiler will first analyse whether there is already a matching
binding that can be merged (i.e. a binding that is a literal attribute
set), and perform the merge, or otherwise create a new recursive set
of bindings in which the entry is inserted with the path iterator
advanced beyond the first name component.
With this, all the logic simply applies recursively until there are no
more nested bindings (i.e. until all iterators are "empty").
Note that this has one (potentially insignificant) deviation from Nix
currently: If a non-mergable value is supplied (e.g. `a.b = 1; a =
2;`), Tvix will emit a *runtime* error (whereas it is *parse* time in
Nix) as the branch which could statically analyse this is currently
unreachable. There's a TODO for this, so we can fix it up later.
