Original change's description:
> devtools: Prepare for service worker UI thread core.
> 
> The thread ServiceWorkerContextCore lives on (the "core thread") will move from
> the IO thread to the UI thread when the ServiceWorkerOnUI feature is enabled.
> 
> This CL makes DevTools aware of the core thread instead of assuming the IO
> thread. This makes https/tests/devtools web_tests pass when the feature is
> enabled.
