This adds a Directory service using

Directory (closures) are put in individual keys.
We don't do any bucketed upload of directory closures (yet), as castore/
fs does query individually, does not request recursively (and buffers).
This will be addressed by store composition at some point.

This drops pretty much all of castore/utils.rs.
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
on the trait level.

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.

In store composition future, we might want to compose this differently,
essentially constructing `ChunkedReader` with another `BlobService`

`build.rs` emits rerun-if-changed statements for all proto files, as

Unfortunately, due to protobufs include path rules, we need to specify
the path to the depot root itself as an include path, at least when
building impurely with `cargo`. This causes cargo to essentially always
rebuild, as it also puts its own temporary files in there.
Unfortunately, tonic-build does not chase down to individual .proto
files that are included.
Disable emitting these `rerun-if-changed` statements for now.
This could cause cargo to not rebuild protos every time, causing stale
data until the next local `cargo clean`, but considering the protos
change not that frequently, and it'll immediately surface if trying to
build via Nix (either locally or in CI), it's a good-enough compromise.

In one function that does the heavy lifting: `ingest_entries`, and three additional helpers:
- `walk_path_for_ingestion` which perform the tree walking in a very naive way and can be replaced by the user
- `leveled_entries_to_stream` which transforms a list of a list of
entries ordered by their depth in the tree to a stream of entries in
the bottom to top order (Merkle-compatible order I will say in the
future).
- `ingest_path` which calls the previous functions.

To make use of the filtering feature, we need to revert the internal walker to a real DFS.
We will therefore just invert the whole tree by storing all of its
contents in a level-keyed vector.
This is horribly expensive in memory, this is a compromise between CPU
and memory, here is the fundamental reason for why:
When you encounter a directory, it's either a leaf or not, i.e. it
contains subdirectories or not.
To know this fact, you can:
- wait until you notice subdirectories under it, i.e. you need to store
any intermediate nodes you see in the meantime -> memory penalty.
- getdents or readdir on it to determine *NOW* its subdirectories -> CPU
penalty and I/O penalty.
This is an implementation of the first proposal, we pay memory.
In practice, we are paying O(#nb of nodes) in memory.
There's a smarter albeit much more complicated algorithm that pays only
O(\sum_i #siblings(p_i)) nodes where (p_1, ..., p_n) is the path to a leaf.
which means for:
A
/ \
B C
/ / \
D E F
We would never store D, E, F but only E, F at a given time.
But we would still store B, C no matter what.

This adds support to retrieve a list of chunks for a given blob to the
BlobService interface.
While theoretically all chunk-awareness could be kept private inside
each BlobService reader, we'd not be able to resolve individual chunks
from different Blobservices - and due to this, not able to substitute
chunks we already have in a more local store.
This function allows asking a BlobService for the list of chunks,
leaving any actual fetching up to the caller (be it through individual
calls to open_read), or asking another store for it.

With the recent introduction of the RootNodes trait, there's nothing in
the fs module pulling in tvix-store dependencies, so it can live in
tvix-castore.
This allows other crates to make use of TvixStoreFS, without having to
pull in tvix-store.
For example, a tvix-build using a fuse mountpoint at /nix/store doesn't
need a PathInfoService to hold the root nodes that should be present,
but just a list.
tvix-store now has a pathinfoservice/fs module, which contains the
necessary glue logic to implement the RootNodes trait for a
PathInfoService.
To satisfy Rust orphan rules for trait implementations, we had to add a
small wrapper struct. It's mostly hidden away by the make_fs helper
function returning a TvixStoreFs.
It can't be entirely private, as its still leaking into the concrete
type of TvixStoreFS.
tvix-store still has `fuse` and `virtiofs` features, but they now simply
enable these features in the `tvix-castore` crate they depend on.
The tests for the fuse functionality stay in tvix-store for now, as
they populate the root nodes through a PathInfoService.
Once above mentioned "list of root nodes" implementation exists, we
might want to shuffle this around one more time.
Fixes b/341.
