Add the primitives necessary to read the client settings from the Nix
daemon wire protocol.
Introducing the read_string primitive. This trivial primitive parses a
read_bytes call, check the bytes are valid utf-8 bytes and wraps the
result in a String.

`appendContext s ctx` will just append a user-crafted context attrs to `s`.
The most important part of this builtin is to perform all the relevant invariant validations
to avoid letting the user craft invalid contexts which can never be built, e.g. invalid store paths,
inexistent derivations, etc.
This version is incomplete and full of TODOs, but passes all the Nix's

Using all the primitives recently implemented to nix-compat to reach
the point where the Nix client start to send us operation requests.
Using a small integration test script (or the VM test, but let's face
it, it's too slow to be useful), we manage to reach the point where
we're able to read a store operation:
2024-03-21T18:53:27.624876Z INFO tvix_daemon: Incoming connection addr=unix
2024-03-21T18:53:27.625312Z INFO worker:perform_init_handshake: tvix_daemon: Trust sent conn=Connection(unix) conn=Connection(unix)

2024-03-21T18:53:27.625488Z INFO worker: tvix_daemon: Operation received op=SetOptions conn=Connection(unix)
We had to take some shortcuts wrt. stderr/log management. The CPP Nix
codebase is a bit confusing in that area. I'll need to spend more time
reading this to fully understand what's happening there. For now,
sending the STDERR_LAST command to the client does the trick.

There were only two things left in there, both a bit messy and only used
for tests:
Some `gen_*_service()` helper functions. These can be expressed by
`from_addr("memory://")`.
The other thing was some plumbing code to test the gRPC layer, by
exposing a in-memory implementation via gRPC, and then connecting to
that channel via a gRPC client again.
Previous CLs moved the connection setup code to
{directory,blob}service::tests::utils, close to where we exercise them,
the new rstest-based tests.
The tests interacting directly on the gRPC types are removed, all
scenarios that were in there show now be covered through the rstest ones

This can be used to validate a Directory closure (connected DAG of
Directories), and their insertion order.
Directories need to be inserted (via `add`), in an order from the leaves
to the root. During insertion, we validate as much as we can at that
time:
- individual validation of Directory messages
- validation of insertion order (no upload of not-yet-known Directories)
- validation of size fields of referred Directories
Internally it keeps all received Directories (and their sizes) in a HashMap,
keyed by digest.
Once all Directories have been inserted, a drain() function can be
called to get a (deduplicated and) validated list of directories, in
from-leaves-to-root order (to be stored somewhere).
While assembling that list, a check for graph connectivity is performed
too, to ensure there's no separate components being sent (and only one
root).
It adds a test suite for these cases, which is much nicer to test than
where we previously had these checks (only in the gRPC server wrapper).
Followup CLs will move the existing putters to use this.
