Is this needed in the content/ layer?  Or can this go in
chrome/common/chrome_switches.h?

For this specific CL, it could go in either content/ or chrome/.

But ChromeDriver can drive content shell, and in the future I'd like to be able
to add other features to this switch, such as exposing synthetic inputs to
ChromeDriver. Other content embedders might also want to know whether they're
running in a WebDriver context.
