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.

This type hides away the lower-level handling of most codemap data
structures, especially to library consumers (see corresponding changes
in tvixbolt).
This will help with implement `import` by giving us central control
over how the codemap works.

There are actually two different types of observers, the ones that
observe the compiler (and emitted chunks from different kinds of
expressions), and the ones that trace runtime execution.
Use of the NoOpObserver is unchanged, it simply implements both
traits.

This has a slight behaviour difference from Nix, in that we don't pin
the time between REPL entries (Nix pins it for the program lifetime),
but this is probably inconsequential as long as it is pinned during an
evaluation.

Add a new derivation target to the passthru of tvix.eval that builds the
benchmark binaries, *and* copies them to the outupts of the derivation
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.

We found a bug after updating to latest tvl-kit which broke
incremental releases.
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.
The bug was introduced by commit:

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.

When encountering a nested binding for the first time, cleanly flip

proceeding with the actual merge.
This reduces the number of points where we have to deal with the (soon
to be slightly more complex) construction of the nested binding
representation.

This adds the scaffolding required for tracking the nesting level (and
appropriately skipping the correct amount of attrpath entries when
inserting nested sets).
In order for all of this to work correctly, we can no longer track
`AttrpathValue` directly in the entries vector as rnix does not allow
us to construct values of that type - so instead we have to track its
inner components.

This sets up the required logic for finding and merging attribute sets
into nested bindings if they exist. This is absolutely not complete
yet and can, at this commit, probably cause undefined runtime
behaviour if nested attributes are specified.
The basic idea is that a new helper function on the `TrackedBindings`
struct is called with each encountered attribute and determines
whether the new entry can be merged into an existing attribute or not.
Right now the only effect this has in practice is that a new error
becomes available if somebody attempts to cause a merge into an
inherited key.

As of this commit, all three types of bindings scopes are compiled the
same way (i.e. compilation of non-recursive attribute sets has been
switched over to the new code paths).
This sets us up for doing the final implementation of nested attribute
sets.
HOWEVER, this breaks the existing implementation of nested attributes
in non-recursive attribute sets. That implementation is flawed and
unworkable in practice, so we need to do this dance to be able to
implement it correctly.
