system-extensions: Introduce InterfaceProvider and set up its connection

This is CL #2 in the chain based on the following design doc:

https://docs.google.com/document/d/1a7ncICMSFfvzXTKeOZ3WkzR7dVI6uI6sz7SPaf4_7W8/edit#

This CL:

* (browser-side) Adds a InterfaceProvider instance to ServiceWorkerHost
* (browser-side) When starting a service worker, we create both
  remote and receiver endpoints for InterfaceProvider. We then pass
  the remote endpoint to ServiceWorkerHost as part of
  CompleteStartWorkerPreparation and we send the receiver endpoint to
  the renderer as part of EmbeddedWorkerStartParams.
* (renderer-side) We save the receiver endpoint of InterfaceProvider
  and bind it on the worker thread in WorkerContextStarted.
* (rendere-side) have ServiceWorkerContextClient implement
  InterfaceProvider.

CL Chain:

[1] Adds a BinderRegistry and registers a Blink Extensions interface
    (https://crrev.com/c/3622154)
[2] Introduce InterfaceProvider and set up its connection
    (This CL)
[3] Add StartWorkerWithEndpointForScope and use it in system extensions
