Mark binding-pattern identifiers with their declaration kind so local destructuring assignments use the normal TDZ and const assignment path. This makes local const destructuring match the environment-backed path. Also teach GetById to expose primitive string virtual index properties before boxing, matching StringGetOwnProperty and GetByValue. Together these fix the SpiderMonkey for-in/of const declaration coverage and the lexical destructuring TDZ test.
