perf(test262): +2.4% pass rate via Function .name/.length and ArrayLike support

Browse Source 
- Array indexOf/includes/lastIndexOf: ArrayLike receiver + fromIndex + SameValueZero
- Function.prototype methods: add .length property via bind_method_static
- Error objects: add .name property via create_kind_error
- Constructor functions: add .name via make_pair + .length via bind_constructor!
- test262: 8497→9009 pass (+512), 38.3%→40.7% rate
