Audio Policy Refactor: reorganise headers inclusion

This patch reoganises the headers inclusion in order to prepare
the split of managerdefault into a manager and a separated lib
of pillar policy elements.

It also moves back the isStrategyActive to the manager to avoid
any dependancies from this pillars to the manager.
