Revision substate CLOSED_FROM_ACCEPTED

Summary:
Ref T9838.

Add a Properties field to Revision, and update a `wasAcceptedBeforeClose` when closing a revision.

Test Plan:
A quick run through the obvious steps (Close with commit/manually,  with or w/o accept) and calling `differential.query` shows the `wasAcceptedBeforeClose` property was setup correctly.

Pushing closed + accepted passes the relevant herald, which was my immediate issue; Pushing un-accepted is blocked.
Test the "commit" rule (Different from "pre-commit") by hacking the DB and running the "has accepted revision" rule in a test-console.
