Support "parentPHIDs" and "ancestorPHIDs" as constraints in project.search API

Ref T12074. Allows querying for project by direct parent (find only immediate children) or any ancestor (find all descendants) using the API.

There's no proper web UI for this since I'm not sure how useful it is, but you can /project/?parent=PHID-PROJ-... or /project/?ancestor=... for now. We can add UI later if/when use cases arise, but it's not immediately clear to me that this is useful to do from the web.

Test Plan:

  • From API, queried with parentPHIDs and ancestorPHIDs, finding direct children only and all descendants, respectively.
  • From web UI, fiddled with ?parent=... and ?ancestor=... to make sure they work too. This isn't intended to be a user-facing feature.
