Avoid WebRTC event log messages when not needed

WebRtcEventLogManager needs to be aware of all peer connections, so
that it may start/stop WebRTC event logging on a per peer connection
basis. This is needed because we only want WebRTC sending RTC event
logs back to Chrome, when Chrome intends to log them. For that reason,
we move the logic from WebRTCEventLogHost into WebRtcEventLogManager,
which will know when these event logs are needed (either for local
or for remote logging).
