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.

It's been a while since the last sled release, and that one binds to a
pretty old version of zstd, requiring workarounds like cl/10090.
Upstream sled main branch currently has zstd halfway patched out (it's
a no-op, but the feature flag and options are still there), and it's in
that state for a year.
Rather than maintaining our own fork of sled, let's just stop using the
compression feature in sled, dropping the version pin to zstd that way,
removing the need for cl/10090.
This doesn't mean we won't reintroduce per-blob compression - but we
probably just won't let sled take care of the compression, but do it
ourselves - which is necessary for more chunked blob storage anyways.
Even though we do drop the feature flag, we still need to explicitly use
use_compression(false).

CLI entrypoint in the tvix-store crate.
Notable changes:
- `fixtures` and `utils` had to be moved out of the `test` cfg, so they
can be imported from tvix-store.
- Some ad-hoc fixtures in the test were moved to proper fixtures in the
same step.
- The protos are now created by a (more static) recipe in the protos/
directory.
The (now two) golang targets are commented out, as it's not possible to
update them properly in the same CL. This will be done by a followup CL
once this is merged (and whitby deployed)
