Add new onboarding screen

[Gio2018]

Goal

• Add the new onboarding screen that includes the "Continue signed out" button as well as privacy and TOS links

Test Steps

• enable the temp.ios.newOnboarding feature flag, or just set the showNewOnboarding = true in LoggedOutViewModel, line 97
• Verify that the new onboarding screen appears (see screenshot)
• Verify that the "Sign up or sign in" behaves as the existing "Continue" button
• Verify that privacy and tos links work

Important

if you enable the feature flag, remember to disable it!

Note

the "Continue signed out" button, currently does nothing and that's expected.
