Pays the given zero-value Invoice using the given amount, retrying if needed based on Retry.

Invoice::payment_hash is used as the PaymentId, which ensures idempotency as long as the payment is still pending. Once the payment completes or fails, you must ensure that a second payment with the same PaymentHash is never sent.

If you wish to use a different payment idempotency token, see pay_zero_value_invoice_with_id.
