Currently it is not possible to distinguish between tracing of the same
*Service type whenever there are multiple of them. Now the instance_name
of ServiceBuilder is passed into the *Service and used in the existing
instrument as the `instance_name` field.
Places that did not already have a instance_name in its context use
`"default"`. In tests I used `"test"`.

This is now supported in the standard library via std::sync::LazyLock,
but requires some manual shuffling around of code.

This switches the PathInfoService trait from using the proto-derived
PathInfo struct to a more restrictive struct, and updates all
implementations to use it.
It removes a lot of the previous conversion and checks, as invalid
states became nonrepresentable, and validations are expressed on the
type level.
PathInfoService implementations consuming protobuf need to convert and
do the verification internally, and can only return the strongly typed
variant.
The nix_compat::narinfo::NarInfo conversions for the proto PathInfo
are removed, we only keep a version showing a NarInfo representation for
the strong struct.
Converting back to a PathInfo requires the root node now, but is
otherwise trivial, so left to the users.

Nodes only have names if they're contained inside a Directory, or if
they're a root node and have something else possibly giving them a name
externally.
This removes all `name` fields in the three different Nodes, and instead
maintains it inside a BTreeMap inside the Directory.
It also removes the NamedNode trait (they don't have a get_name()), as
well as Node::rename(self, name), and all [Partial]Ord implementations
for Node (as they don't have names to use for sorting).
The `nodes()`, `directories()`, `files()` iterators inside a `Directory`
now return a tuple of Name and Node, as does the RootNodesProvider.
The different {Directory,File,Symlink}Node struct constructors got
simpler, and the {Directory,File}Node ones became infallible - as
there's no more possibility to represent invalid state.
The proto structs stayed the same - there's now from_name_and_node and
into_name_and_node to convert back and forth between the two `Node`
structs.
Some further cleanups:
The error types for Node validation were renamed. Everything related to
names is now in the DirectoryError (not yet happy about the naming)
There's some leftover cleanups to do:
- There should be a from_(sorted_)iter and into_iter in Directory, so
we can construct and deconstruct in one go.
That should also enable us to implement conversions from and to the
proto representation that moves, rather than clones.
- The BuildRequest and PathInfo structs are still proto-based, so we
still do a bunch of conversions back and forth there (and have some
ugly expect there). There's not much point for error handling here,
this will be moved to stricter types in a followup CL.

*Node and Directory are types of the tvix-castore model, not the tvix
DirectoryService model. A DirectoryService only happens to send
Directories.
Move types into individual files in a nodes/ subdirectory, as it's
gotten too cluttered in a single file, and (re-)export all types from
the crate root.
This has the effect that we now cannot poke at private fields directly
from other files inside `crate::directoryservice` (as it's not all in
the same file anymore), but that's a good thing, it now forces us to go
through the proper accessors.
For the same reasons, we currently also need to introduce the `rename`
functions on each *Node directly.
A followup is gonna move the names out of the individual enum kinds, so
we can better represent "unnamed nodes".

This uses our own data type to deal with Directories in the castore model.
It makes some undesired states unrepresentable, removing the need for conversions and checking in various places:
- In the protobuf, blake3 digests could have a wrong length, as proto doesn't know fixed-size fields. We now use `B3Digest`, which makes cloning cheaper, and removes the need to do size-checking everywhere.
- In the protobuf, we had three different lists for `files`, `symlinks` and `directories`. This was mostly a protobuf size optimization, but made interacting with them a bit awkward. This has now been replaced with a list of enums, and convenience iterators to get various nodes, and add new ones.

Add instrumentation to the get() and put() implementations of all
PathInfoService.
Use the nixbase32 representation of the digest, not the base64 one.

This provides an implementation of PathInfoService storing PathInfo in
memory up to a certain capacity, then evicting these that have been used
the least recently.
