Adds ProfileTypeRepository

The simplest test-friendly path for determining user profile types.

API note:
UserInfo usage should be deprecated by UserProperties but API is not
yet complete enough to determine policy rules in a generic way,
especially for screenshots.

For now, the profile types must be tested and checked for explicitly.

Useage of this class should be limited to screenshots handling.
