Vincent Ambo 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.
