lavfi: drop planar/packed negotiation support

Browse Source 
The planar/packed switch and the packing_formats list is no longer
required, since the planar/packed information is now stored in the sample
format enum.

This is technically a major API break, possibly it should be not too
painful as we marked the audio filtering API as unstable.
