APM: Implementing configuration loading from AIDL HAL

The main change is to utilize 'getAudioPolicyConfig'
to receive the HAL-provided configuration from
the AudioFlinger and initialize runtime structures
from it.

Accompanying changes:
 - made `libaudiopolicycomponents` a shared library;
 - added or moved around necessary conversion functions;
