AEC3: Parametrize the delay estimator to leverage strong echo paths

Browse Source 
This CL introduces a new behavior for leveraging early information
about the delay that is acquired before the standard delay estimate
has been established.

To simplify the process of setting the parameters for that, the CL
also surfaces the delay estimator parameters to the config struct.
