Handle multiprocess flag in WebView update service.
Instead of letting DevelopmentSettings manage the setting directly and
observing the changes from WebViewUpdateService, have the update service
manage the setting and just expose IPCs for the settings app to use to
get/set the setting. This means we can set a more flexible policy for
whether multiprocess is enabled by default and change it without
touching the settings code, though for now this CL does not change the
behaviour and is just a refactoring.
