Extend VideoCaptureDevice::Client::OnError() to have a tracked_objects::Location param.
Every now and then a bug report would include WebRtc

VideoCaptureDevice::Client::OnError() and has no
origin information. This CL adds that in a way that
clients add the classical FROM_HERE, so that the error
log includes the originating file and line.
