Let's route it to the cc::Scheduler. Only the Browser will have a
SyntheticBeginFrameSource, which is the only class that will really need to know
about the authoritative vsync interval.

Scheduler::CommitVSyncParameters can then override the interval the same way
CompositorVSyncManager::UpdateVSyncParameters used to.
