(core) Disallow the combination of Public Edit access and granular ACLs.

Summary:
- When Public Edit access is enabled, Access Rules page shows a warning and
  prevents saving rules.
- When any ACL rules are present, attempts to set Public access to Editor role
  get downgraded to Viewer role, with a warning notification.
- No checks are made on the server side, so the combination may be achieved via
  the API (but we may block it in the future).

Test Plan: Added a test case.
