Using an actual store path here means we have to copy all of depot into
the Nix store just to rebuild NixOS for a system - this is especially
painful if, like me, you have a rust target/ directory in depot which is
hundreds of GB - nix-build just OOMed on my system with 128GB of RAM!
There's no reason to use a store path here - we can just point to
wherever depot happened to be cloned.

We add a new set of builtins called `import_builtins`, which
will contain import-related builtins, such as `builtins.path` and
`builtins.filterSource`. Both can import paths into the store, with
various knobs to alter the result, e.g. filtering, renaming, expected
hashes.
We introduce `filtered_ingest` which will drive the filtered ingestion
via the Nix function via the generator machinery, and then we register
the root node to the path info service inside the store.
`builtins.filterSource` is very simple, `builtins.path` is a more
complicated model requiring the same logic albeit more sophisticated
with name customization, file ingestion method and expected SHA-256.

(Re-)Adds an error variant that wraps a catchable error kind, which is
used for returning the result of an evaluation.
Previously this would return the internal catchable value, which would
lead to panics if users tried to use these. Somehow this was missed; I
think we need error output tests.

The previous behaviour (enabling `import`, but not allowing e.g.

Now imports from NIX_PATH become enabled by default, unless the user
already overrode that behaviour with something else by setting
`Evaluation::nix_path` manually.

Makes use of the SourceCode field now being stored directly in

to keep a `SourceCode` around just for error formatting.
Updates dependent crates (CLI, serde, tvixbolt) to use this correctly.

With this change it's no longer necessary to track the SourceCode
struct separately from the evaluation for error reporting: It's just
stored directly in the errors.
This also ends up resolving an issue in compiler::bindings, where we
cloned the Arc containing file references way too often. In fact those
clones probably compensate for all additional SourceCode clones during
error construction now.

Some implementations of DirectoryService might not allow retrieval of
intermediate Directory nodes, that are not at the "root".
Think about an object store implementation. The client is doing a
get_recursive anyways to reduce the number of roundtrips.
By documenting the fact we don't need to support looking up intermediate
Directory messages, we can just batch all directories into the same
object, keyed by the root.

That's one possible abstraction to drive builds.
Whenever IO into a store path is requested, we look up the root node,
and in case we don't have it in PathInfoService, but KnownPaths gives us
a Derivation for that output path, trigger a build and await the result.
This recursively might trigger builds for parent paths if they haven't
been built yet.
Another option would be to simply expose a PathInfoService interface for
a builder too, and loop all building into IO via PathInfoService
composition - but let's start with something.
Note tvix-cli doesn't have a configurable BuildService yet, it's plugged
to the DummyBuildService, so whenever it needs to do a build, it'll fail,
but that's how it can be provoked:
```
(builtins.readFile (import <nixpkgs> {}).hello.outPath + "/bin/hello")
[…]
error[E029]: I/O error: /nix/store/cg8a576pz2yfc1wbhxm1zy4x7lrk8pix-hello-2.12.1: builds are not supported with DummyBuildService
--> [code]:1:2
|
1 | (builtins.readFile (import <nixpkgs> {}).hello.outPath + "/bin/hello")
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
Note how this fails, while pure output path calculation
(`(import <nixpkgs> {}).hello.outPath + "/bin/hello")`) still succeeds.

allow to call hashing with substituted input_derivations.
This
1. reduces the number of allocations,
2. prepares substituting `String`s for store paths with proper `StorePath`s without needing a separate derivation struct that allows hashes without `/nix/store` in input_derivations, and
3. keeps the change local to the `Derivation` implementation.
