We actually want to delay fetching until we actually need the file. A
simple evaluation asking for `.outPath` or `.drvPath` should work even
in a pure offline environment.
Before this CL, the fetching logic was quite distributed between
tvix_store_io, and builtins/fetchers.rs.
Rather than having various functions and conversions between structs,
describe a Fetch as an enum type, with the fields describing the fetch.
Define a store_path() function on top of `Fetch` which can be used to
ask for the calculated store path (if the digest has been provided
upfront).
Have a `Fetcher` struct, and give it a `fetch_and_persist` function,
taking a `Fetch` as well as a desired name, and have it deal with all
the logic of persisting the PathInfos. It also returns a StorePathRef,
similar to the `.store_path()` method on a `Fetch` struct.
In a followup CL, we can extend KnownPaths to track fetches AND
derivations, and then use `Fetcher` when we need to do IO into that
store path.

This caught me by accident in an earlier revision of cl/11500 -
I had a `NixString`, wanted to return it as a `String`, so I was naively
calling `s.into()`.
That unfortunately gave me the `Display` implementation of `NixString`,
which quotes strings, causing an annoying error further up the stack.
NixStrings are bytes, we can keep the impl From<NixString> for BString,
but having a `.into()` suddenly do quoting is more than unexpected.

This makes the eval tests and benchmarks standalone Nix derivations and
readTree targets:
```
nix-build -A tvix.cli.eval-nixpkgs-cross-hello-outpath
nix-build -A tvix.cli.benchmark-nixpkgs-attrnames
```
Even without doing any fetches, We need to set `SSL_CERT_FILE`, so
reqwest is able to load its CA roots.

Rather than carrying around an Future in the IngestionEntry::Regular,
simply carry the plain B3Digest.
Code reading through a non-seekable data stream has no choice but to
read and upload blobs immediately, and code seeking through something
seekable (like a filesystem) probably knows better what concurrency to
pick when ingesting, rather than the consuming side.
(Our only) one of these seekable source implementations is now doing
exactly that. We produce a stream of futures, and then use
[StreamExt::buffered] to process more than one, concurrently.
We still keep the same order, to avoid shuffling things and violating
the stream order.
This also cleans up walk_path_for_ingestion in castore/import, as well
as ingest_dir_entries in glue/tvix_store_io.

`ingest_entries` requires that all directories referenced by entries in
the ingestion stream have an explicit entry in the stream.
For example, if the stream contains a file with path `foo/bar`, there
must be an entry that comes later in the stream for the directory `foo`.

Implement a first pass at the fetchTarball builtin.
This uses much of the same machinery as fetchUrl, but has the extra
complexity that tarballs have to be extracted and imported as store
paths (into the directory- and blob-services) before hashing. That's
reasonably involved due to the structure of those two services.
This is (unfortunately) not easy to test in an automated way, but I've
tested it manually for now and it seems to work:

Previously the store ingestion code was coupled to `walkdir::DirEntry`s
produced by the `walkdir` crate which made it impossible to reuse
ingesting from other sources like tarballs or NARs.
This introduces a `IngestionEntry` which carries enough information for
store ingestion and a future for computing the Blake3 digest of files.
This allows the producer to perform file uploads in a way that makes
sense for the source, ie. the filesystem upload could concurrently
upload multiple files at the same time, while the NAR ingestor will need
to ingest the entire blob before yielding the next blob in the stream.
In the future we can buffer small blobs and upload them concurrently,
but the full blob still needs to be read from the NAR before advancing.
