a2dp: improve a2dp sink codec data flushing
...
Let codec decides when rtp packet need to be sent (terminated by MTU size in most case).
LDAC encoding loop can now be terminated by reading if frame_num is written, no 'frame_count' updating is needed.
RTP payload fragmentation can now be implemented more easily based on this.

a2dp: allow codec to hold Props params

Initial Props value are parsed from device settings, further changes are triggered by 'set_param' on a2dp node.
Codec can then use props to tweak its transcoder.

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