cc: Don't discard missed BeginFrames in the DisplayScheduler
Discarding missed BeginFrames likely regresses performance of
<60fps content. We already discard missed BeginFrames in the
cc::Scheduler earlier in the pipeline we shouldn't need to
skip them again later in the pipeline.
All existing correcness tests pass. <60fps content on the
perf dashboard should improve after this lands.
