449dbea456 Mixer: Rework for performance, particularly of the S16 case 
This removes downscaling (halving-add) when multiple voices are
being mixed.  To avoid clipping, and get similar behavior to before,
set the "level" of each voice to (1/voice_count).

Slow paths that were applicable to only M0 chips were removed.

As a side effect, the internal volume representation is now 0 ..
0x8000 (inclusive), which additionally makes a level of exactly 0.5
representable.

Testing performed, on PyGamer: For all 4 data cases, for stereo and
mono, for 1 and 2 voices, play pure sign waves represented as
RawSamples and view the result on a scope and through headphones.
Also, scope the amount of time spent in background tasks.

Code size: growth of +272 bytes

Performance (time in background task when mixing 2 stereo 16-bit voices):
76us per down from 135us (once per ~2.9ms long term average)
(Decrease from 4.7% to 2.4% of all CPU time)
