Added a new api ContentProvider#getTypeAnonymous

- When an app is unable to acquire IContentProvider in contentResolver#getType,
they can only call getTypeAnonymous via activityManagerService.
- default getTypeUnchecked returns getType (to ensure less breaking)
- getType calls are protected by readPermission.
- updated logging of getType calls without readPermisison.
