This is a reland of 60ee70bb40.
The wasm c-api flakes were fixed in https://crrev.com/c/2349293.
Original change's description:
> [wasm] Ensure that only TurboFan code is serialized
>
> We have the implicit assumption that Liftoff code will never be
> serialized, and we start relying on that when implementing new features
> (debugging, dynamic tiering).
>
> This CL makes the serializer fail if the module contains any Liftoff
> code. Existing tests are changed to ensure that we fully tiered up
> before serializing a module (similar to the logic in Chromium).
> The "wasm-clone-module" test needs to serialize the module before
> enabling the debugger.
>
> Note that chrome currently only serializes a module after it fully
> tiered up, so that should be fine. If other embedders need the ability
> to serialize a module in an arbitrary state, we will have to fix this
> later. With this CL we will be on the safe side though and (gracefully)
> fail serialization instead of accidentally serializing Liftoff code.

This change is very mechanical:
own<Foo*> → own<Foo>
vec<Foo*> → ownvec<Foo>
As usual, everything in third_party/ is straight-up copied from upstream.
