feat(tvix/eval): add an AST pretty-printing module r/5143
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.
