[components] Issue https://github.com/mozilla-mobile/android-components/issues/10205: Add support for select credit card prompt
- Implements an override function of `onCreditCardSelect` in `GeckoPromptDelegate`
- Adds a new `CreditCard` data class in `concept-engine`. This is a parallel of GV's
`Autocomplete.CreditCard`. We can't using the existing `CreditCard` from `concept-storage`
since that has encryption dependencies whereas the card number is already decrypted
when it reaches GV.
- Adds a new `SelectCreditCard` in `PromptRequest`
