feat(tvix/eval): allow ignoring locals by prefixing with _ r/4656

This is a common idiom in both Nix and other languages when a local is
declared without actually being used.

Since Tvix warns for unused locals, having this available is useful
and can be included in the final error message as a suggestion if an
unused variable is intentional.
