This "ties the knot" of importing files into a store when referring
to them through path literals, e.g. inside of strings.
I'm not yet sure if this interface is sufficient for
builtins.path (which we haven't implemented at all yet), but it's
enough to wire up eval & store initially.
In the default implementations nothing interesting happens in this
function at all.

Returns the store directory through EvalIO::store_dir.
Note that this is _optional_ in Tvix, as an evaluation can occur in a
context where there simply is no store directory. In those contexts,
`builtins.storeDir` returns `null` in Tvix.
This would only happen in contexts like Tvixbolt (or completely
unrelated use-cases) in practice.

This trait is going to be used to abstract filesystem interactions in
Tvix.
For now, it only contains a `read_to_string` method that closely
mirrors `std::fs::read_to_string`.
As a first step, to see how this works in practice, we will thread
through only this function to the various relevant parts.
Two implementations are provided in tvix-eval itself: A dummy
implementation (which just returns ErrorKind::NotImplemented for all
operations), and a std implementation which delegates to `std`
functions.

This type carries the information required for calculating a
span (i.e. the chunk and offset), instead of the span itself. The span
is then only calculated in cases where it is required (when throwing
errors).
This reduces the eval time for
`builtins.length (builtins.attrNames (import <nixpkgs> {}))` by *one
third*!
The data structure in chunks that carries span information reduces
in-memory size by trading off the speed of retrieving span
information. This is because the span information is only actually
required when throwing errors (or emitting warnings).
However, somewhere along the way we grew a dependency on carrying span
information in thunks (for correctly reporting error chains). Hitting
the code paths for span retrieval was expensive, and carrying the
spans in a different way would still be less cache-efficient. This
change is the best tradeoff I could come up with.

Instead of finding locals by doing 2x O(n) walks over the compiler's
locals list, use a secondary name-based index for resolving locals by
name.
Previously, almost 60% (!!) of eval time on some expressions over
nixpkgs was spent in `Local::has_name`. This function doesn't even
exist anymore now, and eval speed about doubles as a result.
Note that this doesn't exactly make the locals code easier to read,
but I'm also not sure what we can simplify in there in general.
This fixes b/227.
