b9999b292d channelmix: improve mixing setup 
Handle MONO layout as a real layout, not just like FC. This means it
does not share the FC mixing weights.
Only distribute and combine MONO channels when the target is also
MONO, enable normalization in this case.
Otherwise downmix and upmix the mono channels like any other channel,
which will make it respect the upmix and other settings.
Change some tests with this new way of doing things.

Fixes #3010

Refactor the sample test and run the test against itself to make
sure we use all variables at least once.

b7279a1728 channelmix: dont make FC from synthesized FC 
When we have stereo and need to make FC, don't try to upmix the
stereo into FC again.
Fix unit test now that we create FC channels.

6b34b8c44e audioconvert: fix mono channel mix test 
When we have a single MONO channel, distribute and average. Otherwise,
use the logic to do proper mixing.

Adjust the unit test accordingly.

6b0abd2057 channelmix: Improve unknown channel layout handling 
Clamp position to valid range. so that AUX becomes UNKNOWN.
If we have one mono source channel and unknown destination, copy it
to all destination channels.
If we have one mono destination channel and unknown source layout,
average all channels.
Otherwise, pair source and dest channels.
