Change cookie settings strings and sync paused reason message.

This CL changes 'chrome://settings/content' page to display 'Cookies and
site data' instead of 'Cookies'. It changes as well
'chrome://settings/content/cookies' to have 'Cookies and site data' as a
title and 'Clear cookies and site data when you quit Chrome' instead of
'Keep local data only until you quit your browser'. Also, it changes the
message displayed if the user is in sync paused state due to his cookie
settings set to clear on exit to be 'You clear cookies when you quit
Chrome. To keep syncing, change this settings.'. It adds a kill switch
to disable showing this message.
