Fix handling inside Object.defineProperty and Object.defineProperties of length-tracking typed arrays whose backing resizable arraybuffers have been shrunk. Check against the actual element count rather than the original element count. Not an OOB read or write because no memory is accessed, it just didn't throw the expected TypeError exception.
