Fix vp8 simulcast screenshare and perf tests for it

Browse Source 
Simulcast screenshare appears broken due to unrelated changes. It
implicitly relied on SimulcastEncoderAdapter fallback, which happened before
if streams had same resolution. It's not the case anymore. Thus, this CL
adds checks for different frame-rate in simulcast streams.

FullStackTests are also updated to use actual parameters.
