Add a new AsyncRead wrapper, DecompressedReader, that wraps an
underlying AsyncRead, but sniffs the magic bytes at the start of the
stream to determine which compression format is being used out of the
three that are supported by builtins.fetchTarball, and switches to the
correct decompression algorithm adapter dynamically.
This will be used in the implementation of builtins.fetchTarball

We add a new set of builtins called `import_builtins`, which
will contain import-related builtins, such as `builtins.path` and
`builtins.filterSource`. Both can import paths into the store, with
various knobs to alter the result, e.g. filtering, renaming, expected
hashes.
We introduce `filtered_ingest` which will drive the filtered ingestion
via the Nix function via the generator machinery, and then we register
the root node to the path info service inside the store.
`builtins.filterSource` is very simple, `builtins.path` is a more
complicated model requiring the same logic albeit more sophisticated
with name customization, file ingestion method and expected SHA-256.

Initialize a new empty builtins module `fetcher_builtins`, which will
contain the builtins which fetch URLs from the internet:
* fetchurl
* fetchGit
* fetchTarball
* fetchTree (maybe? this is experimental)
These builtins are all implemented in CPP nix at:
https://github.com/NixOS/nix/blob/2.20.2/src/libexpr/primops/fetchTree.cc
These builtins are added to the evaluation context using a similar
mechanism to the derivation builtins, and have been added everywhere
derivation builtins were previously being added.

TvixStoreIO triggers builds whenever IO into a not-yet-built store path
is requested, if it knows how to build that path.

We propagate a `TvixStoreIO` as the `state` of our derivation-specific
builtins in the glue crate.
The evaluators `io_handle` itself is using a Rc<dyn EvalIO>.
An earlier version of TvixStoreIO was also introducing generics over the
different internal services themselves, but we opted for instead
hardcoding this to Arc<dyn …> for the sake of less macro voodoo.

This is an additional test suite on the top of the Nix ones
for context strings matters.
It already smoked out multiple mistakes and potential bugs and non-deterministic result from the evaluator.
It uses a similar technology as the one in the tvix-eval albeit we instantiate a fully fledged evaluator
with in-memory store.
We copy the files instead of symlinking them because crates are built in
isolation, so symlinks cannot work.

- directory in which the castore input nodes are mounted
- working directory for the build command
- scratch paths
- network access y/n
- whether a (static) /bin/sh should be provided
Populate these fields appropriately, and extend the tests in tvix-glue
with a FOD example.

This function converts from a nix_compat::derivation::Derivation to
a BuildRequest.
In addition to the Derivation itself, it needs two lookup functions to
map input paths to their castore nodes.
