Convert wire-format DNS names to uint8_t vectors
Change the output of the conversion functions in dns_util.h and also modernize them to put the output in the return using an optional. Convert the stuff normally taking wire-format DNS names (mostly DnsQuery and DnsResponse) to take the vectors or spans.
A noteworthy change is in TransportSecurityState, which takes domain names, converts to wire format, and then SHA-2 hashes them. The SHA-2 hash code being used does support hashing binary data, but it then returns the hash as a std::array instead of as a string. So I made the changes to keep treating the hashes as std::arrays instead of adding extra code to convert them to/from strings.
No expected behavior changes.
