Expand description

Copy data from one array buffer to another.

srcBuffer must be a (possibly wrapped) ArrayBufferObjectMaybeShared.

This method may throw if unwrapping or allocation fails.

The API for this is modelled on CloneArrayBuffer from the spec: https://tc39.es/ecma262/#sec-clonearraybuffer
