This reverts commit 7bcd2a98be3fa8c246866d6b343c7f94752977b3.
Reason for revert: peerconnection_unittests fails on downstream test runner.
Original change's description:
> Reland "Optimize execution time of RTPSender::UpdateDelayStatistics"
>
> The reland has a lot of additional DCHECKS for easier debugging,
> so in debug builds it will actually be a ~2x slowdown compared to the old code.
> The excessive DCHECKS should be removed in a followup CL.
>
