Require a viewer to load handles

Summary: Unmuck almost all of the we-sort-of-have-viewers-some-of-the-time mess. There are a few notable cases here: - I used Omnipotent users when indexing objects for search. I think this is correct; we do policy filtering when showing results. - I cheated in a bad way in the Remarkup object rule, but fixing this requires fixing all the PhabricatorRemarkupEngine callsites (there are 85). I'll do that in the next diff. - I cheated in a few random places, like when sending mail about package edits. These aren't a big deal. Test Plan: - Grepped for all PhabricatorObjectHandleData references. - Gave them viewers.
