Add a configurable version of the policy engine based on PFW

This patch adds a configurable version of the policy engine
based on the parameter framework.
This configurable engine shall be activated with a flag
USE_CONFIGURABLE_AUDIO_POLICY within BoardConfig.mk

This patch provides the generic configuration as an example.
This configuration provides the same user experience as the default
policy engine.
