audio: move mp_audio->AVFrame conversion to a function

This also makes it refcounted, i.e. the new AVFrame will reference the
mp_audio buffers, instead of potentially forcing the consumer of the
AVFrame to copy the data.

All the extra code is for handling the >8 channels case, which requires
very messy dealing with the extended_ fields (not our fault).
