[Payments] Add ability to bold parts of addresses

[Payments] Add ability to bold parts of addresses

* Add the ability to bold parts of a label.

* Add the ability to show a tertiary label in the PaymentOption, which
  will later be used for phone number display.

- When the phone number can be broken off of the ProfileLabel, it should
  be passed in to the PaymentOption using the new constructor via
  the AutofillAddress class.
