Leonardo de Moura 19533c811b feat(library/script_evaluator): add abstract class that exposes only the API needed by frontend objects
The main motivation is to break the remove the dependency frontends/lean <-- bindings/lua.
This dependency is undesirable because we want to expose the frontends/lean parser and pretty printer objects at bindings/lua.
