audiopolicy: Add support for hybrid mode on A2DP

Add support in AudioPolicyManager to select a module,
device or output based on device type and codec.
Implement hybrid mode with A2DP which enables runtime
switching between HALs for A2DP based on offload support
for specific A2DP codecs.
Optimize A2DP active device change and device config
change in AudioPolicyManager.
