[Payment Handler] Reject with TypeError for bad instrument icons.

Before this patch, failures to download and parse instrument icons would
result in a NotFoundError. This is contrary to the specification, which
states that a TypeError should be thrown:
https://w3c.github.io/payment-handler/#set-method

This patch changes from NotFoundError to TypeError when instrument icons
failed to download or parse.

After this patch, failures to download and parse instrument icons result
in a TypeError.
