Throws a TypeError if key has a numeric index and object has a detached buffer
info: |
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).
...
9.4.5.9 IntegerIndexedElementSet ( O, index, value )
...
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.
