Apply the new A2DP codec config only when passed the check with codec status
In order to apply a new codec config, the Bluetooth framework needs to
re-configure A2DP with remote, to restart the session with the Audio
HAL, and to notify the audio server to reset the output. This is a
heavy task over HALs and frameworks, so we use the current codec status
to ignore redundant codec preferences.
* To change the preference of optional codecs only when there are all
mandatory and optional codecs selectable.
* To apply the new codec preference only when those feeding parameters
or codec specifics are changing.
* Using the current feeding parameters as default settings, and no
codec changed is needed.
