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.

// delegating the const methods and Enable calls to the real GainControl, so
// AGC can still be disabled.

// getting and setting the volume level. It just caches this value to be used
