sprang 5271ea6571 Switch temporal layer impl used for screenshare upper simulcast stream.
Use default temporal layers instead of the RealtimeTemporalLayers one.
When using low fps, having a single stream with much higher bitrate than
the lower simulcast stream causes poor rampup behavior.

Tested manually.
