Add support of negotiating Vp9 SVC in PC test framework.

Browse Source 
SVC support is limited:
During SVC testing there is no SFU, so framework will try to emulate SFU
behavior in regular p2p call. Because of it there are such limitations:
 * if |target_spatial_index| is not equal to the highest spatial layer
   then no packet/frame drops are allowed.

   If there will be any drops, that will affect requested layer, then
   WebRTC SVC implementation will continue decoding only the highest
   available layer and won't restore lower layers, so analyzer won't
   receive required data which will cause wrong results or test failures.
