Throws a TypeError if targetBuffer is detached
info: |
22.2.3.23.1 %TypedArray%.prototype.set (array [ , offset ] )
1. Assert: array is any ECMAScript language value other than an Object with a
[[TypedArrayName]] internal slot. If it is such an Object, the definition in
22.2.3.23.2 applies.
...
8. Let targetBuffer be the value of target's [[ViewedArrayBuffer]] internal
slot.
9. If IsDetachedBuffer(targetBuffer) is true, throw a TypeError exception.
...
15. Let src be ? ToObject(array).
16. Let srcLength be ? ToLength(? Get(src, "length")).
...
