CountBleck a2dc6c4bbb LibJS: Keep the lengths of ArrayBuffers with unowned ByteBuffers fixed ...

The relevant type of ArrayBuffer DataBlock is now a struct containing
both a ByteBuffer* and a size_t size, and not just a ByteBuffer*, with
the size being that of the ByteBuffer. This type of DataBlock is only
used for WebAssembly.Memory (see commit 4fd43a8f96), meaning this
change won't affect any other code. This change is required to pass one
WPT subtest in wasm/jsapi/memory/grow.any.html, since old fixed-length
SharedArrayBuffers after a WebAssembly.Memory growth should keep their
length, while the new buffer after the growth will have the updated
length.
