bluez5: support device capability checks beyond A2DP caps + split sbc-xq to separate codec

Browse source 
We would like to have BT device codec capability checks beyond what's
possible based on A2DP caps.

Split SBC-XQ to a separate codec, and enable it in the device-dependent
check (although currently it just uses the config option).
