Revert of cc: Consider Surface active if frame received recently

Revert of cc: Consider Surface active if frame received recently (patchset #7 id:120001 of https://codereview.chromium.org/1251693002/)

Reason for revert:
This caused regressions in 24/30fps cast tests in stead of improving them.

See crbug.com/514075 for details.

Original issue's description:
> cc: Consider Surface active if frame received recently
>
> Current logic considers a child surface active if
> it has submitted two frames in the last two vsyncs.
> This hurts 30fps or 24fps video use cases, so change
> the heuristic to consider a child surface active if it
> has submitted a frame anytime within the last 3 vsyncs.
