Original change's description:
> Use new arraybuffer deleter interface in d8
> 
> With this cl we start using the custom deleter to free externalized
> array buffers. This also allows us to keep wasm memories registered
> with the wasm memory tracker and thereby to propagate that a memory
> is wasm allocated over postMessage calls.
