0abc66ad91 feat(tvix/eval): add an AST pretty-printing module
This implements serde::Serialize for the rnix AST through a wrapper
type, and exposes a function for serialising the AST into
a (pretty-printed JSON) string representation.

This can be used to debug issues with the AST, and to display an AST
reprsentation in tools like tvixbolt.

Serialize is implemented manually because we don't own any of the
structs and the way to traverse them is not easily derived
automatically, and this is quite verbose. We might be able to condense
it a little bit, but at the same time it's also fairly straightforward.

03a3189a3d feat(tvix/eval): Initial impl of builtins.match
Implement an *initial* version of builtins.match, using the rust `regex`
crate for regular expressions. The rust regex crate definitely has
different semantics than nix's regular expressions - but we'd like to
see how far we can get before the incompatibility starts to matter.

This consciously leaves out any sort of memo for compiled regular
expressions (which upstream nix also has) for the sake of expediency -
in the future we should implement that so we don't have to compile the
same regular expression multiple times.

5eb89be682 feat(tvix/eval): Implement builtins.fromJSON
Using `serde_json` for parsing JSON here, plus an `impl FromJSON for
Value`. The latter is primarily to stay "dependency light" for now -
likely going with an actual serde `Deserialize` impl in the future is
going to be way better as it allows saving significantly on intermediary
allocations.

c46025d520 fix(tvix/eval): support string identifiers in inherits
This updates rnix-parser to a version where inherits provide an
iterator over `ast::Attr` instead of `ast::Ident`, which mirrors the
behaviour of Nix (inherits can have (statically known) strings as
their identifiers).

This actually required some fairly significant code reshuffling in the
compiler, as there was an implicit assumption in many places that we
would have an `ast::Ident` node available when dealing with variable
access (which is then explicitly only not true in this case).

bb47baf638 feat(corp/tvixbolt): persist state in tvixbolt's URL
This makes it possible to enter something into tvixbolt and then share
the link with someone else.

Suggested by Profpatsch originally.

b3cc4c8c2c chore(tvix/eval): bump rnix-parser to latest HEAD
This bumps rnix-parser to a commit that should be unaffected by the
Nix >= 2.4 bug that prevents it from cloning repositories with filters.

dea6d9b73b chore(tvix/eval): add dependency on codemap-diagnostic
This is a crate for source-span based error reporting. Since all of
our spans are already codemap spans, it is a good starting point.

We have to figure out quite a bit of logic for neat error printing;
later on if we want fancier presentation we might want to look at one
of the other libraries in this space like miette.

8655440ae3 feat(corp/tvixbolt): check in initial tvixbolt version
This is the code backing the small site currently deployed at
https://tazj.in/blobs/nixbolt/index.html

This relies on a newer version of Tvix than is available in depot and
a bunch of other stuff that isn't public yet, so for now no build file
is provided as this is heavily work-in-progress.
