Do not show "Add to Home Screen" info bar if WebAPK is installed

Non-WebAPK web apps rely on a property in site preferences to determine
whether the web app has been installed. If a user clears Chrome's data
via Settings->Apps->Chrome->Storage->"Clear Data" site preferences are
cleared.
This CL adds a way for determining whether a WebAPK is installed which
works even after a user clears Chrome's data.
