Reviewed by Jean-Yves Avenard.

When the internal media pipeline additional logging flag is enabled, we check frame rate for all script transforms on input and output.
This might tell us whether:
- frame rate gets broken before the script transform (there is some related logging in libwebrtc already).
- frame rate gets broken by the script transform.
