encoding: treat TLV-TYPE zero as invalid

 * Use tlv::Invalid to indicate an invalid Block, instead of
   UINT32_MAX (which is a valid type), thus fixing bug #4726
 * Introduce Block::isValid as a replacement for Block::empty
   and soft-deprecate the latter
 * Improve test coverage of Block and tlv::readType
