Reason for revert: Speculative revert (some perf test are failing)
Original change's description:
> Make new pacer padding more like old one
>
> The (currently unused) new pacer code path was implemented with what
> was intended as a more careful padding strategy.
> Unfortunately this doesn't work as well as expected due to the fact
> that the padding budget cannot build up underuse.
>
> I made another CL that could fix that, but I think it adds complexity
> for dubious gains. It also will make it more difficult to find any
> potential regression when switching to the new path, should one occur.
> See https://webrtc-review.googlesource.com/c/src/+/144563
>
> Therefore, this CL makes the new code path choose RTX payload in the
> same way as is currently done.
