This adds an additional nar-bridge-pathinfo command.
It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.
It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.
It's one building component as soon as we have store composition (which
we currently don't, so don't use this).
It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.

This validates the size of reference digests in the PathInfo message,
as well as inside the narinfo submessage. If narinfo is set, they need
to parse to StorePath, and have the same digest there as in the PathInfo
message.
`proto::tests::pathinfo::validate_references` needed to be updated,
because we actually did not populate the proper references before.

This partially fixes b/312 and gets FUSE to work again on MacOS.
It is mostly small type changes and an update to fuse-backend-rs because
upstream currently doesn't work with MacFuse. It also sets the default
FUSE thread count on MacOS to 1 because otherwise the mount command will
hang when shutting down as only one thread gets ENODEV and all the others
just keep blocking.
