Reduce callsites to "ArcanistDifferentialRevisionStatus" in Phabricator

Summary:
Ref T2543. These are currently numeric values, like "0" and "3". I want to replace them with strings, like "accepted", and move definitions from Arcanist to Phabricator.

To set the stage for this, reduce the number of callsites where Phabricator invokes `ArcanistDifferentialRevisionStatus`.

This is just the easy ones. I'll hold this until the release cut.

Test Plan:
- Called `differential.find`.
- Called `differential.getrevision`.
- Called `differential.query`.
- Removed all reviewers from a revision, saw warning.
- Abandoned the no-reviewers revision, no more warning.
- Attached a revision to a task to get it to show the state icon with the status on a tooltip.
- Viewed revision bucketing on dashboard.
- Used `bin/search index` to reindex a revision.
- Hit the "Land Revision" endpoint.

I didn't explicitly test these cases:

  - Doorkeeper Asana integration, since setup takes a thousand years.
  - Disambiguation logic when multiple hashes match, since setup is also very involved.
  - Releeph because it's Releeph.
