Essentially applying the same change as in https://codereview.webrtc.org/2023413002 in more locations. There's only one change affecting production code: enabling the warning for webrtc/media:rtc_media. The rest are test changes. With these changes, the only place the warning is disabled is in the Windows implementation of webrtc/modules/video_capture:video_capture_internal_impl, which is harder to fix, since it relies on sample code from the Windows SDK.
