[Master port] Audio HAL: Add optional Destination to SinkMetadata 

This patch ports a change to the HAL interfaces done in master in
order to have the same Audio common HAL interface in both AOSP and master.
This is needed as the Bluetooth HAL uses the audio common HAL and needs
to be frozen in the same state in both AOSP and MASTER.

Currently this is used to indicate the output device
when the input stream is from an intermediate processing
module like MSD.
