This is the first CL needed to add a new `AdaptiveModeLevelEstimator` feature that makes AGC2 more robus to VAD mistakes: the level estimator discards estimation updates when too few consecutive speech frames are observed. In this CL, the state of the estimator is defined in a separate struct so that in a follow-up CL a new member of that type can be added to hold a temporary state (that can be either confirmed or discarded).
