Bug 2055093 - Cherry-pick upstream libwebrtc commit bb91915655 r=webrtc-reviewers,dbaker

Upstream commit: https://webrtc.googlesource.com/src/+/bb91915655ac409c482e0bf25304605a06435608
       In VideoCaptureDS use Stop instead of StopWhenReady

       As reported on Firefox an Insta360 Link 2 Pro camera has a driver bug
       that leaves the camera light on until reboot when using StopWhenReady
       during teardown of a capture session.

       See https://bugzilla.mozilla.org/show_bug.cgi?id=2055093

       Using Stop instead works around the driver bug, and better matches
       Chromium's DirectShow backend.

       Bug: none
