How about having the integrity string in IntegrityMetadata? 
I think it'd be better to have information about the integrity into one place.

integrity string was converted to IntegrityMetadataSet in
SubresourceIntegrity::ParseIntegrityAttribute, even IntegrityMetadata 
 has the integrity string, it is difficult to get it from
integrity_metadata(IntegrityMetadataSet).

   params.SetParserDisposition(parser_state);
