Reason for revert:
Temporarily disabled tests on chromium side (https://codereview.chromium.org/2764933002)
Original issue's description:
> Revert of [wasm] Transferrable modules (patchset #13 id:280001 of https://codereview.chromium.org/2748473004/ )

> Reason for revert:
> Breaks layout tests:
> https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064/builds/14312

> Original issue's description:
> > [wasm] Transferrable modules
> >
> > We want to restrict structured cloning in Chrome to:
> > - postMessage senders and receivers that are co-located
> > in the same process
> > - indexedDB (just https).
> >
> > For context, on the Chrome side, we will achieve the postMessage part
> > by using a mechanism similar to transferrables: the
> > SerializedScriptValue will have a list of wasm modules, separate from
> > the serialized data stream; and this list won't be copied cross
> > process boundaries. The IDB part is achieved by explicitly opting in
> > reading/writing to the serialization stream. To block attack vectors
> > in IPC cases, the default for deserialization will be to expect data
> > in the wasm transfers list.
> >
> > This change is the V8 side necessary to enabling this design. We
> > introduce TransferrableModule, an opaque datatype exposed to the
> > embedder. Internally, TransferrableModules are just serialized data,
> > because we don't have a better mechanism, at the moment, for
> > de-contextualizing/re-contextualizing wasm modules (wrt Isolate and
> > Context).
> >
> > The chrome defaults will be implemented in the
> > serialization/deserialization delegates on that side. For the v8 side
> > of things, in the absence of a serialization delegate, the V8
> > serializer will write to serialization stream. In the absence of a
> > deserialization delegate, the deserializer won't work. This asymmetry
> > is intentional - it communicates to the embedder the need to make a
> > policy decision, otherwise wasm serialization/deserialization won't
> > work "out of the box".
