Bug 1828517 - Vendor libwebrtc from 416bc06a6a

Upstream commit: https://webrtc.googlesource.com/src/+/416bc06a6aa3735e33edcec5c1ffb68beb310924
    Disable stop CNG after a timeout.

    This is still a behavior that we want, but a more careful rollout is needed.

    (cherry picked from commit 48d784225972b7dd0542acfad7cd2d0eed25ad1c)
