Before using the cookie jar APIs to add and remove CHROME_CONNECTED
cookie, |IOSChromeSigninClient| used to call the
AccountConsistencyService::RemoveAllChromeConnectedCookies to delete
these cookies. This was removed as part of CL
https://chromium-review.googlesource.com/c/chromium/src/+/2421669.

This CL fixes the AccountConsistencyService service to actually remove
the CHROME_CONNECTED cookie when the user signs out of Chrome as this is
no longer called by IOSChromeSigninClient.
