Subject: Add API to set the codec preference for specific device

Add the APIs that would use in developer optin for setting
the codec config preference and getiting the codec status.
Expose the APIs first, some of the implementations
will be done later.
Add equals function to BluetoothLeAudioCodecConfig for
comparison usage
