Remove several pieces of audit-related code

Summary: Ref T10978. This code (mostly related to the old ADD_AUDIT transaction and some to the "store English text in the database" audit reasons) is no longer reachable.

Test Plan:
Grepped for removed symbols:

- withAuditStatus
- getActionNameMap (unrelated callsites exist)
- getActionName (unrelated callsites exist)
- getActionPastTenseVerb
- addAuditReason
- getAuditReasons
- auditReasonMap

Also audited some commits.
