[ios] Configures Save CreditCard InfobarBanner.

- Configures the CreditCard Banner for presentation.
- Implements Banner related methods like performInfobarAction
and dismissBannerWhenInteractionIsFinished.
- On InfobarCoordinator detachView (which is called when the Infobar
view needs to be removed) we only dismiss the VC if they have been
created. This is needed since now a CreditCard InfobarBanner can be created
while other one is being presented, since replace is not supported
it will discard the new Infobar, thus calling detachView in an Infobar
that was never presented.
