[Payments] Fix crash in payment manifest parser.

Before this patch, parsing payment method manifest with invalid UTF8
in the URL of the "supported_origins" would hit a CHECK() in GURL
constructor.

This patch rejects URLs that have invalid UTF8 before constructing a
GURL object and fingerprints that are not ASCII.

After this patch, the parser rejects payment method manifests with
invalid UTF8 in the URL of the "supported_origins".
