Now that we can bind (potentially lazy, potentially lambda-containing)
values in the REPL and then reference them in subsequent evaluations,
it's important that the values to which we construct shared references
are shared across those subsequent evaluations - otherwise, we get
panics due to unknown source map locations, or dropped weak references
to globals.
This change assigns both the globals and the source map as fields on the
Repl after the first evaluation, and then passes those in (to the
EvaluationBuilder) on subsequent evaluations.
On the EvaluationBuilder side, there's some panicking introduced - this
is intentional, as my intent is for the builder to be configured
statically enough that panicking is the best way to report errors
here (it's always a bug to misconfigure an Evaluation, and we'd never
want to handle it dynamically).

Juggle around the internals of the tvix-cli crate so that we expose the
Repl as a public type with a `send` method, that sends a string to the
repl and *captures all output* so that it can be subsequently asserted
on in tests. Then, demonstrate that this works with a single (for now)
REPL test using expect-test to assert on the output of a single command
sent to the REPL.
As the REPL gets more complicated, this will allow us to make tests that
cover that complex behavior.

Make constructing of a new Evaluation use the builder pattern rather
than setting public mutable fields. This is currently a pure
refactor (no functionality has changed) but has a few advantages:
- We've encapsulated the internals of the fields in Evaluation, meaning
we can change them without too much breakage of clients
- We have type safety that prevents us from ever changing the fields of
an Evaluation after it's built (which matters more in a world where we
reuse Evaluations).
More importantly, this paves the road for doing different things with
the construction of an Evaluation - notably, sharing certain things like
the GlobalsMap across subsequent evaluations in eg the REPL.

Allow binding variables at the REPL's toplevel in the same way the Nix
REPL does, using the syntax <ident> = <expr>. This fully, strictly
evaluates the value and sets it in the repl's "env", which gets passed
in at the toplevel when evaluating expressions.
The laziness behavior differs from Nix's, but I think this is good:

Provide a new interface for forcing a flush of otlp traces and use this
interface to shutdown otlp prior to exiting tvix-store, either if the
tool was stopped with a SIGTERM or ended regularly.
This also fixes an issue where traces were not even exported if for
example we just imported 10 paths and never even emitted more than 256
traces. The implementation uses a mpsc channel so a flush can be done
without having to wait for it to complete. If you want to wait for a
flush to complete you can provide a oneshot channel which will receive a
message once flushing is complete.
Because of a otlp bug `force_flush` as well as
`shutdown_tracer_provider` need to be executed using `spawn_blocking`
otherwise the function will deadlock. See

This shouldn't be part of the PathInfoService trait.
Pretty much none of the PathInfoServices do implement it, and requiring
them to implement it means they also cannot make use of this calculation
already being done by other PathInfoServices.
Move it out into its own NarCalculationService trait, defined somewhere
at tvix_store::nar, and have everyone who wants to trigger nar
calculation use nar_calculation_service directly, which now is an
additional field in TvixStoreIO for example.
It being moved outside the PathInfoService trait doesn't prohibit
specific implementations to implement it (like the GRPC client for the
`PathInfoService` does.
This is currently wired together in a bit of a hacky fashion - as of
now, everything uses the naive implementation that traverses blob and
directoryservice, rather than composing it properly. I want to leave
that up to a later CL, dealing with other parts of store composition
too.

`builtins.filterSource` is very simple, `builtins.path` is a more
