[ServiceWorker] Eliminate ServiceWorkerDispatcherHost::resource_context_

This CL lets ServiceWorkerProviderHost get the resource context from
ServiceWorkerContextWrapper directly, rather than getting from
ServiceWorkerDispatcherHost, then we no longer need to keep a resource
context in each ServiceWorkerDispatcherHost.

[ServiceWorker] ServiceWorkerProviderHost no longer needs ServiceWorkerDispatcherHost

In legacy IPCs era, ServiceWorkerProviderHost was relying on
ServiceWorkerDispatcherHost to send legacy IPCs to the renderer
process, now it has switched to Mojo and no longer needs
ServiceWorkerDispatcherHost to do any work.

This CL removes such a dependency aiming to make code logic around
ServiceWorkerDispatcherHost clearer, which will facilitate the future
refactor work on ServiceWorkerDispatcherHost.

[ServiceWorker] ServiceWorkerContextCore no longer needs to manage SWDispatcherHosts

After https://chromium-review.googlesource.com/c/chromium/src/+/1068514,
no code will try to find the specific ServiceWorkerDispatcherHost for a
given renderer process, so this CL removes the mapping management of
ServiceWorkerDispatcherHosts inside ServiceWorkerContextCore, in the
meantime simplifies ServiceWorkerDispatcherHost a little.

Once we make clear about how to do what content::mojom::ServiceWorkerDispatcherHost.OnProviderCreated() does now in another way, then we can eliminate ServiceWorkerDispatcherHost class.

[ServiceWorker] Make ServiceWorkerDispatcherHost not a BrowserMessageFilter any more

As Service Worker IPCs are all in Mojo now, we no longer use
ServiceWorkerDispatcherHost to handle any legacy IPCs, its only usage is
to implement mojom::ServiceWorkerDispatcherHost interface, so, it no
longer needs to be a BrowserMessageFilter.
This CL makes ServiceWorkerDispatcherHost not a BrowserMessageFilter any
more, but still keeps its Mojo interface being associated with the
legacy IPC channel.

In future once we make clear of those potential races with some legacy
IPCs like navigation IPCs, we can consider putting
mojom::ServiceWorkerDispatcherHost on a dedicated Mojo message pipe, or
we'd remove mojom::ServiceWorkerDispatcherHost completely if we can find
an alternative/clear way to achieve the same goal.
