Introduce APIs that allow for the creation of JavaScript strings without copying the underlying native string into the engine. The APIs fall back to regular string creation if the engine's external string APIs are unavailable. In this case, an optional boolean out-parameter indicates that the string was copied, and the optional finalizer is called if given.
