[Card Benefits][Metrics] Add selected without benefit 2+ card metric

For the card benefits project, we are going to begin tracking form event
metrics when users have 2 or more server cards on Payments Autofill,
with at least 1 card eligible to show benefits. We also plan to migrate
the existing benefit form event enums to a new, benefit-specific form
event enum class.

This CL adds `kSuggestionWithoutBenefitSelectedWithMultipleServerCards`
to a new benefit-specific form event enum class. This CL also logs this
enum to the `Autofill.FormEvents.CreditCard.Benefits` histogram.

The new form event enum will allow us to track lift in selection rate:
(kSuggestionWithBenefitSelectedWithMultipleServerCards +
kSuggestionWithoutBenefitSelectedWithMultipleServerCards) /
kSuggestionWithBenefitShownWithMultipleServerCards
