  Update comment on getCustomDiagID; NFC

These APIs should almost never be used in Clang, so documenting that
more clearly. The problem is that the diagnostics are never associated
with a diagnostic group, so users have no way to control warning
behavior associated with the diagnostic. That makes for a poor user
experience. Instead, use a real diagnostic whenever possible or the API
taking a CustomDiagDesc as a last resort.
