options: drop deprecated --vd/--ad codecs selection features

Only simple selection works now. Using "-" to terminate codec selection
remains in the code (might get undeprecated).

       A minor difference is that --hwdec-api=no (which used to be the default)
       now actually does not preload any interop layer, while the new default
       ("") uses the value of --hwdec.

     Specify a priority list of audio decoders to be used, according to their
     decoder name. When determining which decoder to use, the first decoder that
     matches the audio format is selected. If that is unavailable, the next
     decoder is used. Finally, it tries all other decoders that are not
     explicitly selected or rejected by the option.
 
-    Specifying family names is deprecated. Entries like ``family:*`` prioritize

     ``-`` at the end of the list suppresses fallback on other available
     decoders not on the ``--ad`` list. ``+`` in front of an entry forces the

     normal decoder auto-selection! Both of these methods are deprecated.
