Initial support for partitioning cookies for isolated apps.

This CL adds experimental support for letting installed apps request isolated
storage in their manifest.  An isolated app will have its own cookie store
that is not shared with other apps or normal pages, even if they share an
origin.  The feature is currently behind a --enable-experimental-app-manifests
flag.
