Revert "Reland "[wasm] Compile JS to WASM wrappers asynchronously""
This reverts commit 801930f5f5
.
Reason for revert: blink layout tests failure https://bugs.chromium.org/p/v8/issues/detail?id=9554
Original change's description:
> Reland "[wasm] Compile JS to WASM wrappers asynchronously"
>
> Original CL had an issue with builtins being accessed through the
> isolate after the isolate died. See:
> https://ci.chromium.org/p/v8/builders/try.triggered/v8_win64_rel_ng_triggered/b8907837534672203296
>
> Initial upload is the original CL and the following patch sets will
> attempt to fix it.
