Audio: Enable dynamic on-the-fly AEC3 configuration updates for the suppressor gain computation

This CL refactors suppression gain to allow dynamic configuration changes without requiring reinitialization. This allows switching to a specific ML-REE configuration once the linear mode is used.

These changes are bitexact when not running the neural residual echo estimator. The refinement in MovingAverageSpectrum does not introduce  any change when the residual residual echo estimator is disabled. When running neural residual echo estimator, there is a reduction of initial echo blips for recordings that manifest such issue.
