Revert "Allows FEC generation after pacer step."

Browse Source 
This reverts commit 75fd127640bdf1729af6b4a25875e6d01f1570e0.

Reason for revert: Breaks downstream test

Original change's description:
> Allows FEC generation after pacer step.
> 
> Split out from https://webrtc-review.googlesource.com/c/src/+/173708
> This CL enables FEC packets to be generated as media packets are sent,
> rather than generated, i.e. media packets are inserted into the fec
> generator after the pacing stage rather than at packetization time.
> 
> This may have some small impact of performance. FEC packets are
> typically only generated when a new packet with a marker bit is added,
> which means FEC packets protecting a frame will now be sent after all
> of the media packets, rather than (potentially) interleaved with them.
> Therefore this feature is currently behind a flag so we can examine the
> impact. Once we are comfortable with the behavior we'll make it default
> and remove the old code.
> 
> Note that this change does not include the "protect all header
> extensions" part of the original CL - that will be a follow-up.
