[Description] For FPO + Vactive scenarios we must check that all non-FPO pipes have VACTIVE margin to allow it. The previous check only confirmed that there is at least one pipe that has vactive margin, but this is incorrect as the vactive display could be using two pipes (MPO) where the desktop plane has vactive margin, and the video plane does not.
