perkj 825eb58d59 Revert of Remove SendPacer from ViEEncoder (patchset #13 id:240001 of https://codereview.webrtc.org/1917793002/ )
Reason for revert:
Fails in the waterfall here:

https://build.chromium.org/p/client.webrtc/builders/Win32%20Debug/builds/7832/steps/rtc_media_unittests/logs/stdio

Original issue's description:
> Remove SendPacer from ViEEncoder
>
> This CL moves the logic where the ViEEncoder pause if the pacer is full to the BitrateController. If the queue is full, the controller reports a bitrate of zero to  Call (and BitrateAllocator)
>
