Allow play.google.com links redirect to ARC.

This CL adds a special case so play.google.com links can be redirected
to ARC even if both the URL of the current page and the one we are
navigating to have the same domain (google.com), this should allow the
user to redirect the search straight to the Play Store (on ARC).

Bug:  763455 
Test: Adding a handful of cases to check this via unittest.

Modify ArcNavigationThrottle rules

Instead of special casing for play.google.com links, we can allow the
ArcNavigationThrottle to query ARC for apps when the navigation is
taking case from and to the google.com domain iff the host is different.
