Summary [GStreamer][WebRTC] A few uninitialized variables were added in 304213@main

In the new code added in 304213@main there are computations like `m_totalAudioEnergy += m_audioLevel * m_audioLevel * duration`, but `m_audioLevel` is only computed if we take the `if (auto audioLevelMeta = gst_buffer_get_audio_level_meta(buffer)) {` branch. Therefore m_audioLevel & co might be uninitialized - same for video tracks. All variables should always be initialized in any case.
