It's being deprecated by V8.
Explicitly allocate a new ArrayBuffer and copy the data instead.

Fixes: #52234

Some suggestions to avoid the copy when the size is the same.

(I do wonder now that we can't shrink the backing store in place, is there any benefit in allocating them on the V8 heap instead of using externally-managed buffers that we can realloc()? At least when we shrink externally-managed buffers we don't need to do the copy and it'll be cheaper. But that can be left as a TODO after we get rid of the deprecated API).
