Restore VideoCodecInitializer to use only the 1st stream maxFramerate

Browse Source 
This is a partial fix for regression introduced in
https://webrtc-review.googlesource.com/c/src/+/125461

Currently, the OveruseFrameDetector::OnTargetFramerateUpdated is called
only then the encoder is reconfigured, with the default maxFramerate.

Changing it from default 5 to 60, or even 30 made the detector too
sensitive and it caused adaptation down due to CPU overuse even on
powerful machines.
