rtc-svc: Fixes for screen with spatial layers

Several fixes to make screen work with spatial layers:

-last_source is set based on superframe count to ensure
 last_source is the previous source for all spatial layers
-source_last_TL0 is used to ensure last_source corresponds
 to the LAST reference.
-scene detection is only done on SLO with full resolution,
 and the state of the detection is passed on to the other
 spatial layers.
-source_sad is allowed for every spatial layer.
-cyclic refresh counter on distance to scene change/max_q
 is added to the layer context and updated per spatial layer.
-allow for prediction from lower spatial layer in nonrd_pickmode.

Unittest added for screen with spatial layers.

No change in stats for default 1 layer encoding.
