Plumb the notification about audio HAL services update to APM
AudioFlinger registers a callback with libaudiohal to receive
notifications when new HAL services get registered. It relays
the notification to AudioPolicyManager via AudioSystem /
IAudioPolicyService interface.
Because AF / APM only interact via Binder interfaces and APM's
interface gets registered later than AF's, the notification
from AF is made asynchronous.
Bug: 149854039
Test: audio test on a regular phone configuration
audio test on a phone with MSD audio HAL module
