[w3c/webpayments] [Tokenized Card Payment] Replace usage of 'last4' with 'suffix' (#211)

_Ian requested some feedback on this proposal, which I am happy to provide. Note that my feedback should not be taken as an endorsement of the proposal itself._

In https://w3c.github.io/webpayments/proposals/tokenized_cards.html#response

dictionary TokenizedCardResponse : BasicCardResponse {
    required DOMString cardLast4;
             DOMString tokenType;
             DOMString tokenRequesterId;

Although many cards and networks sanitize to the last four digits, there are some edge cases where that doesn't happen. I would recommend renaming this to something along the lines of `cardSuffix`.
