Update Chrome/Opera support for MediaStreamTrack's stop() method (#17229)
Update Chrome/Opera support for MediaStreamTrack's stop() method (#17229)

The original data is from wiki migration:
https://github.com/mdn/browser-compat-data/pull/1248

The commit implementing the stop() method is here:
https://chromium.googlesource.com/chromium/src/+/ffbe9abb72c71abaf8623c56c9ad7f6ee04f48b4

That suggests Chrome 31 by naive date mapping.

But Chrome 32 was confirmed by evaluating
`MediaStreamTrack.prototype.stop` on Chrome 31 and 32 on BrowserStack.
