Allow <webview> to access URLs in the origin of the app embedding it.
With r422474 creation of blob: URLs with origin of a chrome-extension://
was locked down. However, the case of a <webview> loading an
accessible_resource from its embedder and creating a blob: is disallowed.
This CL adds permission for <webview> to create such URLs in the origin
of its embedder.
This CL is based on work by nick@chromium.org.
