bluez5: enable duplex for aptx-ll

Browse source 
aptX-LL sink devices may send back mSBC encoded data corresponding to
microphone input.  It appears to be enabled when the bidirectional link
is set in the caps, and the device also supports this.

Implement mSBC decoding in the duplex channel.

Tested to be working on Avantree Aria Pro.
