6b3c3c9826 refactor(tvix/eval): add macros for generating Value casters
The casting methods of `Value` are pretty verbose, and actually
incorrect before this commit as they did not account for inner thunk
values.

To address this, we first attempt to make them correct by introducing
a standard macro to generate them and traverse the inner thunk(s) if
necessary.

This is likely to be a performance hit as it will now involve more
cloning of values. We can do multiple things to alleviate this, but
should do some measurements first.

5ee89bcf5c fix(tvix/eval): inherit scope poisoning data in nested contexts
Scope poisoning must be inherited across lambda context boundaries,
e.g. if an outer scope has a poisoned `null`, any lambdas defined on
the same level must reference that poisoned identifier correctly.

0a13d267f0 fix(tvix/eval): thread thunk forcing errors through correctly
With this, if an error occurs while forcing a thunk (which is very
likely) it is threaded through to the top by wrapping it in the
ErrorKind::ThunkForce variant.

We could use this to generate "stacktrace-like" error output if we
wanted, or simply jump through and discard everything except the
innermost error.

377ba19d75 feat(tvix/eval): ensure all errors always carry a span
Previously error spans were optional because the information about
code spans was not available at runtime. Now that this information has
been added, the error type will always carry a span.

This change is very invasive all throughout the codebase. This is due
to the fact that many functions that are called *by* the VM expected
to return `EvalResult`, but this no longer works as the span
information is not available to those functions - only to the VM
itself.

To work around this the majority of these functions have been changed
to return `Result<T, ErrorKind>` instead and an accompanying macro in
the VM constructs the "real" error.

Note that this implementatino currently has a bug where errors
occuring within thunks will yield the location at which the thunk was
forced, not the location at which the error occured within the code.
This will be fixed soon, but the commit is large enough as is.

55d21a1389 refactor(tvix/eval): store spans instead of nodes in Warning/Error
Another step towards being able to report accurate errors. The codemap
spans contain strictly more accessible information, as they now retain
information about which input file something came from.

This required some shuffling around in the compiler to thread all the
right information to the right places.

c269b44f41 feat(tvix/eval): track source spans for upvalues
With this change, the upvalue data instructions used by finalisers for
thunks and closures track the source span of the first identifier that
created the upvalue (if the same value is closed over multiple times
the upvalue will be reused, hence only the first one).

To do this the upvalue struct used by the compiler's scope now carries
an identifier node, which had to be threaded through quite a few
places.

These are again a bit tricky in terms of emitted errors. The main
error is that the condition is not a boolean, which means that the
jump inspecting the condition must derive from the condition itself to
return an error at the correct position.

For other parts of the expression, it is simply the node itself.

805c1870ee feat(tvix/eval): track source spans for or operator
This one is tricky, specifically the span used for the final jump. I
decided that it makes sense to use the attrpath node, as the final
jump is the one that jumps *over* the default value, so the effect of
this is more closely related to the selector than the default.

It might be more correct to pass through the `or` token itself and
point to this for the jumps, but it depends a bit on what shape of
errors we could end up producing from this.

fea7f90a7f fix(tvix/eval): thread Display & PartialEq through to thunk values
If a thunk is already evaluated, there are cases where due to the
memoisation implementation something might observe a value wrapped in
a thunk.

In these cases, the implementation of `Display` and `PartialEq` must
delegate to the underlying value.

Note that there are a handful of other cases like these which we need
to cover.

It is a little tricky to write integration tests for these directly,
especially as some of the open-upvalue optimisations coming down the
pipe will reduce the number of observable thunks.

One test that covers a part of this behaviour is currently
disabled (needs some more machinery), but it's being brought back in
the next commits.

38d3db5fb8 feat(tvix/eval): implement NixAttrs::iter()
Implementing iteration over NixAttrs requires a custom iterator type
in order to encapsulate the different representations. The BTreeMap
for example has its own iterator type which needs to be encapsulated.

This is mostly boilerplate code, but for a change some simple unit
tests have been added in.

7d5dca7ba3 chore(tvix/eval): provide 'static references to "name"/"value"
These static strings show up a bunch when dealing with the internals
of attribute sets, and having them available as static references is
required.

Due to the way const expressions are evaluated, taking a reference to
the existing NixString::NAME / NixString::VALUE items does not work
and the references themselves need to be const-evaluated.

80713f207e refactor(tvix/eval): encapsulate all thunk-forcing logic in module
The VM previously took care of repeatedly forcing a thunk until it
reached an evaluated state. This logic is now encapsulated inside of
the `Thunk::force` implementation.

In addition, force no longer returns a reference to the value by
default, leaving it up to callers to decide whether they want to
borrow the value or not (a helper is provided for this).

23a5caabec feat(tvix/eval): construct attribute sets lazily
This thunks the construction of attribute sets. Because Tvix does not
currently have a "strict output" mode, a test had to be disabled that
now displays a thunk representation.

The test will be re-enabled once that is available.
