Make DiffusionCommitSearch accept modern (string) constants

Summary:
Depends on D19650. Ref T13197. Allow `SearchCheckboxesField` to have a "deprecated" map of older aliases, then convert them to modern values.

On the API method page, show all the values.

This technically resolves the issue in PHI841, although I still plan to migrate behind this.

Test Plan:
{F5875363}

- Queried audits, fiddled with `?status=1,audited`, etc.
