  -----------
  [LTO] Introduce helper functions to add GUIDs to ImportList (NFC) (#105555)

The new helper functions make the intent clearer while hiding
implementation details, including how we handle previously added
entries.  Note that:

- If we are adding a GUID as a GlobalValueSummary::Definition, then we
  override a previously added GlobalValueSummary::Declaration entry
  for the same GUID.

- If we are adding a GUID as a GlobalValueSummary::Declaration, then a
  previously added GlobalValueSummary::Definition entry for the same
  GUID takes precedence, and no change is made.
