Convert Audit comment rendering to standard infrastructure

Summary: Ref T4896. Depends on D10055. This uses core rendering stuff for audit comments, and fixes all the wonkiness with inlines so we can actually land the migration.

Test Plan: Viewed, previewed and edited various types of comments in Diffusion.
