[Merge M-53] Credit card editor for PaymentRequest UI.

[Merge M-53] Credit card editor for PaymentRequest UI.

When user taps on an incomplete autofill credit card or [+ ADD CARD]
button, the card editor launches.

For server cards, the editor shows uneditable card information and lets
the user set the billing address.

For local cards, the editor shows the following fields.

1) A list of icons for supported card types.

2) The card number input with Luhn validation and formatting. Required
   field.

3) The name on card input. Required field.

4) The month and year dropdowns. January of this year by default for new
   cards.

5) The billing address dropdown with only complete addresses on disk and
   an option to add a new address. Required field.

6) A checkbox for saving the new card on disk. Checked by default,
   so it behaves similar to autofill settings.
