Sort extensions in menu on page interaction status

This groups extensions into three buckets:

* Extensions that are accessing (can access) the page's data
* Extensions that want to access the page's data
* Extensions that can't access the page's data

Labels are used as headings for each of these three buckets. No label is
added for groups that don't have a corresponding extension.
