[Autofill local card migration settings page] Add IsMigratable attribute to each CreditCardEntry.

A card is migratable only when this card's card number and expiration date is valid and does not have a duplicated server card.

The validation and duplication check is only supported in the c++ side, so we add a new attribute called IsMigratable when we create each CreditCardEntry in autofill_util in order to check the migration requirement later.

The following CLs will be:

1. Use the added IsMigratable, syncStatus and experimental flag to check the migration requirement.

2. Display the migration button to the user when requirements meet.

3. Trigger migration when user click on the button with a new API call.
