Enabling new-style 'virtual viewport' pinch by default on ChromeOS

Enabling new-style 'virtual viewport' pinch by default on ChromeOS

ChromeOS virtual keyboard depends on the virtual viewport to support overscrolling. Enabled it by default on ChromeOS and removed it as an experiment from about:flags. Also added the experiment to Android since we'll eventually want to enable it there too.
