webrtc-audio-processing: Fix build with -Werror=return-type

* apply the work around from:
  https://gitlab.freedesktop.org/pulseaudio/webrtc-audio-processing/-/merge_requests/28
  which is still needed for 1.3 version:

  webrtc-audio-processing-1.3/webrtc/modules/audio_processing/agc2/adaptive_mode_level_estimator.cc: In function 'float webrtc::{anonymous}::GetLevel(const webrtc::VadLevelAnalyzer::Result&, LevelEstimatorType)':
  webrtc-audio-processing-1.3/webrtc/modules/audio_processing/agc2/adaptive_mode_level_estimator.cc:45:1: error: control reaches end of non-void function [-Werror=return-type]
     45 | }
        | ^
  webrtc-audio-processing-1.3/webrtc/modules/audio_processing/audio_processing_impl.cc: In function 'webrtc::GainControl::Mode webrtc::{anonymous}::Agc1ConfigModeToInterfaceMode(webrtc::AudioProcessing::Config::GainController1::Mode)':
  webrtc-audio-processing-1.3/webrtc/modules/audio_processing/audio_processing_impl.cc:117:1: error: control reaches end of non-void function [-Werror=return-type]
    117 | }
        | ^

  webrtc-audio-processing-1.3/webrtc/modules/audio_processing/audio_processing_impl.cc:1853:13: error: control reaches end of non-void function  -Werror=return-type]
   1853 |             default:
        |             ^~~~~~~

* this can now be dropped from meta-webosose, where it was since:
