[RDSG] Use Feature Engagement to trigger Default-on message

Added the following events:
- desktop_site_settings_page_opened
If the user has opened the desktop site settings page.
- request_desktop_site_default_on_iph_trigger
If the message has been shown.
- desktop_site_default_on_primary_action
If the user has accepted the message.
- desktop_site_default_on_gesture
If the user has explicitly dismissed the message.

The initial client side config matches current product behavior.
Will make adjustment via server side config in follow-up CL.
