PaymentHandler: Replace 'enabledMethods' array with 'method' string

The related spec change:
  https://github.com/w3c/payment-handler/pull/276

Payment Handler feature is behind a flag:
  chrome://flags/#service-worker-payment-apps

FYI, the original field type was `repeated string`, and the changed
field type is `optional string`. So, if `enabledMethods` data is
stored in a previous version, when reading the `method` field in a new
version, the protobuf will read the first element of `enabledMethods`.
Therefore, DB migration is not required.
