Moves delegate for InfobarBadgeTabHelper from LocationBarMediator to
BadgeMediator. LocationBarViewController now implements the BadgeConsumer
protocol to receive signals from BadgeMediator. LocationBarViewController's
implementation of BadgeConsumer looks odd, because it still only supports
one badge. Ultimately a separate view controller owned by BadgeCoordinator will
be the BadgeMediator's consumer.
