PaymentRequest specific card issuer icons
This patch changes CreditCard.getIssuerIconDrawableId() to return
PaymentRequest specific icons, because only PaymentRequest is using
these. The icons are larger than autofill icons. These files have been
run through optimize-png-files.sh. For now they are used only on
Android, the first platform to have PaymentRequest implementation.
