DescriptionReland of Don't send FEC for H.264 with NACK enabled. (patchset #1 id:1 of https://codereview.webrtc.org/1692783005/ )
Reason for revert:
Disabling tests on memcheck that time out due to using real VP8 encoders.
Original issue's description:
> Revert of Don't send FEC for H.264 with NACK enabled. (patchset #5 id:80001 of https://codereview.webrtc.org/1687303002/ )
>
> Reason for revert:
> Broke the VerifyHistogramStatsWithRed test on the Windows DrMemory Full bot and Linux Memcheck bot. Please fix the test and reland.

> > The H.264 does not contain picture IDs and are not sufficient to
> > determine that a packet may be skipped. This causes retransmission
> > requests for FEC that are currently dropped by the sender (since they
> > should be redundant).
> >
> > The receiver is then unable to continue without having the packet gap
> > filled (unlike VP8/VP9 which moves on since it has a consecutive stream
> > of picture IDs).
> >
> > Even if FEC retransmission did work it's a huge waste of bandwidth,
> > since it just adds additional overhead that has to be unconditionally
> > transmitted. This bandwidth is better used to send higher-quality
> > frames.
