The outer fingerprint used for store path calculation is always a sha256
digest. This includes both input and output-addressed store paths.
We used a NixHash here, which can also represent other hash types, and
that had a bunch of annoyances:
- Whenever we had the bytes, we had to wrap them in a NixHash::Sha256().
- Things like AtermWriteable had to be implemented on NixHash,
even though we then had an assertion it was only called in the
NixHash::Sha256 case.

...in `Derivation`.
This is more type-safe and should consume less memory.
This also removes some allocations in the potentially hot path of output hash calculation.

Passing a StorePathRef is annoying if we only (already) have a
StorePath.

This allows getting a Derivation struct producing the passed output
path.

We need to not only store a map from drv path to hash derivation modulo,
but also keep the original Derivation struct - because we'll use that
later to trigger builds.

Rather than passing strings around, use a StorePathRef.
This makes things a bit more typesafe, and more aligned with what we
want to do in b/264.

This are leftovers from the "reference scanning" approach (which we
didn't end up using).
We still want a concept of known paths, so we can trace IO into
storepaths back to the build recipe that'll produce it, so let's keep
the rest of this struct around.

We calculate the input context by performing the union of context
over all input of the derivation.
Then, we just pass the rest of it to the remaining machinery.
Finally, we re-emit an `outPath` and a `drvPath` containing the expected
contexts.

cl/9364 did introduce a warning here, which is visible when building in
release mode - or invoking `cargo bench` in tvix-glue.

Currently we produce wrong drvPaths for a large number of packages
that use fetchurl (but not fetchurlBoot, which is what stdenv uses).
A simple reproducer is `pkgs.perl538`.
I debugged this down to the root cause, which is the fact that tvix
doesn't realize that the mapping from FOD-paths to outputHash is
*NOT* a 1:1 mapping. It is a many-to-one mapping. You can have
lots of different FODs with the same outputHash or even the same
outPath. For example, perl538.src and perldevel.src use the same
source tarball but a different `version`.
Anyways, I have found the root cause but have run out of time for a
while, so I've added a panic!() to in the spot where we have a logic
bug in order to call it out.

There's various bits and pieces in tvix-cli that use both the store and
evaluator, as well as nix-compat. For example, builtins.derivation, as
well as the reference scanning implementation.
This "glue code" currently isn't accessible from anywhere else, but it'd
be very useful if it were.
Move it out into a `glue` crate, and make `tvix-cli` a consumer of it.
All the KnownPaths setup and passing around, as well as NIX_PATH
handling is also something that should probably be moved into the glue
crate as well, but that's something left for a future CL.
