Markus Handell e59fee87fb ZeroHertzAdapterMode: activate earlier. 
Careful analysis of logs related to the requesting of refresh
frames from the source revealed an uncomfortable truth:
zero-hertz mode activates first when the first frame has been
received in the VideoStreamEncoder, because the number of simulcast
layers can only be computed when frame dimensions are known. This
fact means that the currently implemented logic for requesting
refresh frames is noneffective.

Fix this by
1. Activating zero-hertz mode prior of knowing the final layer
count. This causes refresh frame requests to happen without any
frames received from the source.
2. Making layer count dynamically configurable. Zero-hertz mode
considers layer quality unconverged after such a reconfiguration.
