Revert "Replaced temporal_layer_thresholds_bps[] field with num_temporal_layers."

Browse Source 
This reverts commit d2ed0a4c9e7f04060d8e3358eb0006c31579bb86.

Reason for revert: Breaks downstream projects.

Original change's description:
> Replaced temporal_layer_thresholds_bps[] field with num_temporal_layers.
> 
> temporal_layer_thresholds_bps served only one purpose: its size was used
> to infer number of temporal layers. I replaced it with num_temporal_layers,
> which does what is says.
> 
> The practical reason for this change is the need to have possibility to
> distinguish between cases when VP9 SVC temporal layering was/not set
> through field trial. That was not possible with
> temporal_layer_thresholds_bps[] because empty vector means 1 temporal
> layer.
>
