WebRequest: Extensions intercepting navigation requests don't need access to initiator.

This CL makes the following changes to the host permission model for the
Web Request and Declarative Net Request APIs:

- To intercept a navigation request (sub-frame or main-frame request),
  extensions don't need host permissions to the request initiator. They only
  need access to the request url. This is unlike sub-resource requests which
  need host permission to both the request url and initiator.
- If an extension has access to a navigation request's initiator but it's access
  to the request url is withheld, the extension isn't implicitly granted access
  to the request. This is unlike sub-resource requests where the extension will
  be granted access.
