Clear old verified flush IDs when doing OrderingBarrier.

Clear old verified flush IDs when doing OrderingBarrier.

If a command buffer generates sync tokens but doesn't validate them
(letting a different command buffer in the same stream do that), then
its queue of unverified flush ids will grow without bound. It can clear
them out with little overhead by checking which ones are verified after
every GpuChannelHost::OrderingBarrier call.
