AGC: Add a histogram for clipping adjustment

AGC: Add a histogram for clipping adjustment

This new histogram will log a value every time input clipping is
detected. The value is a boolean, with "true" meaning that the gain
was in fact adjusted in response to the detected clipping, and "false"
meaning that adjustment was not allowed due to kClippedLevelMin.
