C++ MessageTrait name attribute [DEVINFRA-1034]

Description

Implements the request in #1240 for a name attribute in the C++ MessageTrait class.

It results in something like:

template <>
struct MessageTraits<sbp_msg_acknowledge_t> {
  static constexpr sbp_msg_type_t id = SbpMsgAcknowledge;
  static constexpr char *name = "MSG_ACKNOWLEDGE";
...

It's failing on master too, looking at the latest auto submodule update commit.
