VP9 SVC: Add new level to constrain inter-layer pred. Add another level (INTER_LAYER_PRED_ON_CONSTRAINED) to the inter-layer prediction control. This new level enforces the condition that a given spatial layer S can only do inter-layer prediction from the previous spatial layer (S - 1) from the same time/superframe.
