[builtins] implement Array.prototype[@@iterator] in TFJ builtins 

Implements the variations of CreateArrayIterator() in TFJ builtins
(ArrayPrototypeValues, ArrayPrototypeEntries and ArrayPrototypeKeys), and
provides two new Object types with numerous maps which identify certain
behaviours, which will be useful for inlining.

Removes src/js/array-iterator.js entirely

Also adds support for printing Symbol literals inserted by the Parser during
desugaring when FLAG_print_builtin_ast is set to true.
