Raphael Kubo da Costa e90879097c IWYU: Add <cmath> for fabsf() and powf(), switch to C++ versions
Fix the build with libstdc++ after 496cedfe5 ("AEC3: Reverberation model:
Changes on the decay estimation") by including the missing header:

    ../../modules/audio_processing/aec3/reverb_model_estimator.cc: In constructor ‘webrtc::ReverbModelEstimator::ReverbModelEstimator(const webrtc::EchoCanceller3Config&)’:
    ../../modules/audio_processing/aec3/reverb_model_estimator.cc:61:21: error: ‘fabsf’ was not declared in this scope
           reverb_decay_(fabsf(config.ep_strength.default_len)),
                         ^~~~~
    ../../modules/audio_processing/aec3/reverb_model_estimator.cc:61:21: note: suggested alternative: ‘labs’
           reverb_decay_(fabsf(config.ep_strength.default_len)),
                         ^~~~~
                         labs
    ../../modules/audio_processing/aec3/reverb_model_estimator.cc: In member function ‘void webrtc::ReverbModelEstimator::UpdateReverbDecay(const std::vector<float>&)’:
    ../../modules/audio_processing/aec3/reverb_model_estimator.cc:206:15: error: ‘powf’ was not declared in this scope
           decay = powf(2.0f, -exp_candidate * kFftLengthBy2);
                   ^~~~

While here, also switch to the C++ versions of those functions: std::fabs()
and std::pow() respectively.
