This lets the VM emit warnings when it encounters situations that

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`
instead of `super`. This new convention is much easier to understand
especially for users that are new to Nix and Nixpkgs.
This change is notable in the Nixpkgs project code. I added a note
mentioning that the official documentation hasn't been update with
this information. The documentation is currently undergoing an
overhaul and that is why I believe this hasn't been reflected in the
nixpkgs documentation as of yet.

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.
