Reland "Convert ExtensionHostMsg_RequestWorker/WorkerResponseAck to mojo"

This is a reland of commit 708ab44c7c94f08b924167ce8bcab3959c632bd0

This CL was reverted due to a failure to
ExtensionApiTestWithSwitch.ExtensionTracing. But the test has been
failed occasionally before merging the original CL even after reverting, so it seems that the original CL wasn't culprit.

Original change's description:
> Convert ExtensionHostMsg_RequestWorker/WorkerResponseAck to mojo
>
> This CL is step 2 for adding extensions.mojom.ServiceWorkerHost and
> converts ExtensionHostMsg_RequestWorker/WorkerResponseAck to mojo.
>
> ServiceWorkerHost and EventRouter for extensions should be associated
> each other and bound to the worker thread. Currently EventRouter mojo
> interface is legacy IPC associated, so we follow below steps to avoid
> flaky.
>
> Steps:
> 1) Get an associated interface for mojom::ServiceWorkerHost from the
>    IPC::SyncMessageFilter as mojom::EventRouter
> 2) Convert ExtensionHostMsg_* to mojom::ServiceWorkerHost.
> 3) Add an AssociatedInterfaceRegistry for service worker and obtain
>    intefaces for both mojom::ServiceWorkerHost and mojom::EventRouter.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
