  Throws a TypeError if key has a numeric index and object has a detached

  9.4.5.5 [[Set]] ( P, V, Receiver)

  ...
  2. If Type(P) is String, then
    a. Let numericIndex be ! CanonicalNumericIndexString(P).
    b. If numericIndex is not undefined, then
      i. Return ? IntegerIndexedElementSet(O, numericIndex, V).

  ...
  3. Let numValue be ? ToNumber(value).
  4. Let buffer be the value of O's [[ViewedArrayBuffer]] internal slot.
  5. If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
