Move AGC2 config ToString to the right place and update Validate()

Browse Source 
The APM config to string mapping must be in one place (namely,
in `audio_processing.cc`). This CL moves the AGC2 config to string
impl to the right place.

This CL also updates `GainController2::Validate()` and adds the
missing unit tests for the parameters that have recently been added.

Stack buffer size in `AudioProcessing::Config::ToString()` increased
because of the extra params. Syntax near `multi_channel_capture` fixed.
Output string format verified with a JS linter.
