Remove APM internal usage of EchoCancellation

This CL:
 - Changes EchoCancellationImpl to inherit privately from
   EchoCancellation.
 - Removes usage of AudioProcessing::echo_cancellation() inside most of
   the audio processing module and unit tests.
 - Default-enables metrics collection in AEC2.

This CL breaks audioproc_f backwards compatibility: It can no longer
use all recorded settings (drift compensation, suppression level), but
prints an error message when such settings are encountered.

Some code in audio_processing_unittest.cc still uses the old interface.
I'll handle that in a separate change, as it is not as straightforward
to preserve coverage.
