[Payments] Replace deprecated OverviewModeBehavior in PaymentUiService

Since OverviewModeBehavior has been deprecated in favor of
LayoutStateProvider, this CL replace PaymentUiService's
OverviewModeBehavior with LayoutStateProvider.

In order to do that, this CL also provides an accessor for
ChromeTabbedActivity's LayoutStateProvider.

* The CL that introduced OverviewModeBehavior to payment code:
