Description:
This change adds Next Steps cards section on HTML New Tab Page. The change from native NTP
is that Next Steps section can't be controlled by the user.

Steps to test this PR:
General note - the view model wasn't changed so all the logic (e.g. cards randomization or hiding after 7 days) should work the same as on the native NTP.

1. Clean app data and run the app from Xcode.
2. Disable Email Protection as needed.
3. Set internal state and enable HTML New Tab Page using a feature flag.
4. Verify that you see 5 Next Steps cards.
5. Remember cards order, close and reopen window and verify that the order is different.
6. Dismiss all cards one by one, close and reopen window and verify that there are no cards.
7. Quit the app, clean app data and run the app from Xcode (then set internal user state and enable HTML NTP feature flag).
8. Click Duck Player card, open Duck Player. Go back to NTP and verify that Duck Player card is gone.
9. Click Default Browser card, set browser as default and verify that the card is gone.
10. Click Dock card and verify that app is added to Dock. The card is not removed and the button doesn't update to "Added to Dock" which is a known issue to be addressed separately.
11. Click Import card, import bookmarks and verify that the card is gone.
12. Enable Email Protection and verify that the card is gone.
