Per Åhgren 78026754a7 AEC3: Utilize shadow filter output to respond to audio path changes 
This CL adds functionality to use the shadow filter output instead
of the main filter output for cases when the former is better than
the latter. One case when that happens is when there have been an
echo path change, either in the acoustic path, in the audio buffers
or due to some active audio processing effects being applied on
the device.

The CL causes less echo leaks, in particular on devices with
active render processing.
