Drop references to now gone PaymentAddress and AddressErrors interfaces

[tidoust]

The PaymentAddress and AddressErrors interfaces were dropped from Payment Request in w3c/payment-request#955

The "Payment Method: Basic Card" document still references them in the definition of BasicCardChangeDetails and BasicCardErrors, making the IDL inconsistent as a whole.

@ianbjacobs, looking at minutes from a recent group call, I see that goal might be to deprecate the specification entirely. That would be a more radical way to fix the inconsistency. If it still gets published as a Note with IDL, it would still be good to resolve it properly.

Done. Spec was gutted.
