(Collect_Interps): When only one interpretation has been found, set N's
Entity and Etype to that interpretation, otherwise Entity and Etype may

completed with pragma Import.
Add missing escaping of all-caps word 'CPP' in error messages.

(Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
Is_Remote_Call_Interface to identify RACW types in a stable and
consistent way. We used to rely in this predicate on the privateness of
the designated type and its ancestors, but depending on the currently
visible private parts, this caused false negatives. We now uniformly
rely on checks made at the point where the RACW type is declared.
