A2dpSrc: DEV-UI support for Blutooth Audio codec.

Due to enhancements in the DEV-UI by AOSP, Blutooth Audio
codec menu showing nothing in developer settings. Due to
length mismatch of the bluetooth_a2dp_codec_titles and
bluetooth_a2dp_codec_summaries in settings leading to
this issue.

Issue has been fixed by introducing QVA codecs too, so
that length won't mismatch.
