Sam Zackrisson 41478c7c1b Remove AudioProcessing::gain_control() getter
This change also resolves a bug in audioproc_f:
The implicit ApplyConfig calls to enable gain control settings in
aec_dump_simulator.cc:377-406 [1] are overwritten by the ApplyConfig
call on line 500 using a config from line 292.

Compared to a ToT build including a fix for that bug, these changes
are bitexact on a large number of aecdumps.
