options: remove --mixer and --mixer-channel, turn them into alsa/oss subopts

These two options were supported by ALSA and OSS only. Further, their
values were specific to the respective audio systems, so it doesn't make
sense to keep them as top-level options.

-``--mixer=<device>``
-    Use a mixer device different from the default ``/dev/mixer``. For ALSA
-    this is the mixer name.

-    This option will tell mpv to use a different channel for controlling
-    volume than the default PCM. Options for OSS include **vol, pcm, line**.
-    For a complete list of options look for ``SOUND_DEVICE_NAMES`` in
-    ``/usr/include/linux/soundcard.h``. For ALSA, you can use the names e.g.
-    "``amixer scontrols``" displays, like **Master, Line, PCM**.

-        ALSA mixer channel names followed by a number must be specified in the

-        be converted to PCM,1.
