phabricator: add a "phabstatus" show view

We add a "phabstatus" show view (called as "hg show phabstatus") which

revision and displays their status.

The revisions shown is a subset of that shown by "work" view, only
including revisions with known by Phabricator.

Differential Revision: https://phab.mercurial-scm.org/D7506
