Original change's description:
> When waiting on Main thread, keep the reporter until main frame reporter is terminated
>
> There are cases that a FrameReporter with no compositor damage is blocked on another reporter (long main thread work).
>
> In such cases the reporter should be kept around until the reporter on main thread is terminated and based on that reporter having damage or not, be reported as having partial_update or no_update.
>
> Also added an UMA metric to track the number of reporters we discard in order to prevent renderer-hang ("Graphics.Smoothness.Diagnostics.DiscardedDependentCount")
>
