Throws a TypeError if object has valid numeric index and a detached buffer
(honoring the Realm of the current execution context)

3. If Type(P) is String, then
a. Let numericIndex be ! CanonicalNumericIndexString(P).
b. If numericIndex is not undefined, then

xi. If Desc has a [[Value]] field, then
1. Let value be Desc.[[Value]].
2. Return ? IntegerIndexedElementSet(O, intIndex, value).

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