Pipe `SkipUnknownTriples` flag through TBD file YAML and v5 JSON parsers. When set, target strings with an unknown architecture or platform are dropped from the parsed `InterfaceFile` instead of producing a fatal parse error. Additionally, "unknown architecture"/"unknown platform" parse errors are collapsed into a single "unknown target" message. resolves: rdar://175690963
