Implement app process model isolation.

The process grouping logic is unfortunately duplicated in SiteInstance and
RenderView. URLs that are part of extension X's web extent get converted into
a pseudo URL of the form chrome-extension://X/path. This groups pages from an
extension app and its offline resources into the same process.

The rest is mostly plumbing and passing data around.
