  -----------
  [TableGen] Use heterogenous lookups with std::map (NFC) (#115810)

Heterogenous lookups allow us to call find with StringRef, avoiding a
temporary heap allocation of std::string.

This patch introduces alias:

  using DiagsInGroup = std::map<std::string, GroupInfo, std::less<>>;

because the raw type is a bit mouthful.
