audiohal: Support stateful downmixer effects
Fraunhofer's downmixer has additional buffering, this is incompatible
with how DownmixerBufferProvider used to process incomplete buffers.
Now the effects HIDL wrapper delivers frameCount updates in
audiobuffers to the server side. This fixes playback of multichannel
sound streams.
Bug: 36181621
Test: play 5.1 track from Play Music

Correctly operate on input and output buffers in DownmixerBufferProvider
Note that playback is a bit choppy, need to investigate further.

Re-implement HIDL effect processing using FMQ and IMemory
Result: no hwbinder calls due music processing.
Test: make, use Play Music with effects, check traces
