IMPORTANT NOTE:
    CL depends on another CL in frameworks/base

AudioProductStrategies offers the possibility to dynamically
translate attributes to stream types (and vice versa) within
audio policy engine.
Legacy engine has hard coded rules to maintain the translation
service.

This patch removes the hardcoded translation within the helper
and replaces them by AudioProductStrategy APIs.

Test: AudioPolicyTests: AudioProductStrategiesAllStreamsTest
It loops on all stream types supported by strategy and ensures
device selection matches. Hard coded stuff would prevent right device
selection.
Test: CTS: AudioTrackTest AudioRecordTest
Test: audio smoke test on sailfish, walleye blueline
