feat(tvix/cli): implement `builtins.derivation` r/5769

This uses the actual upstream Nix code for
`builtins.derivation` (which is not a primop in C++ Nix) to implement
`builtins.derivation` as a wrapper around `builtins.derivationStrict`.

We're doing it this way to ensure that our thunking logic is correct.
An initial Rust-native rewrite (see e.g. cl/7363) is pretty difficult
to debug while there are still other issues to root out, but
eventually we might want to turn this into native code.
