AGC2 dummy module: fixed gain param, APM integration, audioproc_f adaptation

In preparation of coming CLs that will add an AGC interface to make the
gain controller injectable.

This CL simplifies AGC2 (dummy sub-module of audioproc_f) since it only
implements the fixed digital mode with hard-clipping - i.e., no limiter
is used.
The AGC2 config now includes the fixed gain to apply and audioproc_f
has been adapted accordingly.
Finally, this CL slightly simplifies the AGC2 integration into APM.

This CL is a continuation of https://codereview.webrtc.org/2995043002/
