Replace factory that takes optional FieldTrialView with a constructor that takes non-optional reference to the same interface - all callers already guarantee it is not nullptr Replace several local IsEnabled/IsDisabled helpers with the same helpers in FieldTrialView In CongestionWindowPushbackController tests pass field trials bypassing global field trial string Bug: webrtc:42220378 Change-Id: Ic49ad78919d834a5e3b9b69545d3b39088023a75 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/349900 Commit-Queue: Danil Chapovalov <danilchap@webrtc.org> Reviewed-by: Erik Språng <sprang@webrtc.org> Cr-Commit-Position: refs/heads/main@{#42270}
