Add audio policy API changes for audio offload
Changes to the API of audio policy for audio offload support:
- Add isOffloadSupported() function
- Add OUTPUT_FLAG_OFFLOAD
- Extend AudioOutputDescriptor to include a sharing count for direct outputs
- Pass audio_offload_info_t when opening output streams
