rtc: Add dynamic spatial layers to external RC test

Add test to change the number of spatial layers on
the fly. This requires a few fixes in the svc encocder:
1) fix the svc condition in adjust_q_cbr() for adjustment
   based on resolution change
2) add flag to detect change in number of spatial layers,
   and use it to reset the cyclic refresh.

Dynamic dropping/enabling layers based on bitrate
to be added next.
