[turbofan] Add support for copy-on-write element stores. This extends JSNativeContextSpecialization with support for stores to fast object/smi element backing stores that are marked as copy-on-write. In this case we first call the CopyFixedArray builtin to take a copy of the elements backing store, and then store the new elements back to the object, and finally perform the actual element store.
