Re-enable infobar for default browser prompt

[simonhong]

Use upstream's infobar for default browser asking

1. Set non brave as a default default browser
2. Launch brave with clean profile
3. Create NTP and relaunch
4. Check default browser infobar is visible
5. Click set default button and relaunch
6. Check infobar is not visible anymore
7. Set non brave as a default browser and relaunch Brave
8. Check infobar is visible
9. Dismiss infobar by clicking x and relaunch
10. Check infobar is not visible

Note: after dismiss, infobar is not shown again. To make visible, we should provide refresh period via griffin.
Or, this dismiss flag is cleared when user set Brave as a default.

From the bool ShouldShowDefaultBrowserPrompt(Profile* profile), it checks refresh days after dismissed.
As we don't provide this value yet, it's not shown again. This will be handled by #25930

    base::StringToInt(variations::GetVariationParamValue(
                          "DefaultBrowserInfobar", "RefreshPeriodDays"),
