Subject: MAINT-1175: Properly pass LLRegistry's COMPARATOR to underlying map.
 Although LLRegistry and LLRegistrySingleton have always defined a COMPARATOR
 template parameter, it wasn't used for the underlying map. Therefore every
 type, including any pointer type, was being compared using std::less. This
 happens to work most of the time -- but is tripping us up now. Pass
 COMPARATOR to underlying std::map. Fix a couple minor bugs in
 LLRegistryDefaultComparator (never before used!). Specialize for const char*.
 Remove CompareTypeID and LLCompareTypeID because we now actively forbid using
 LLRegistry<std::type_info*, ...>; remove only known reference
 (LLWidgetNameRegistry definition).
