[Ada] Mimic the C++ ABI when passing class-wide conversion actuals
This patch does not affect the behavior of Ada-only code but improves
consistency with the code generated by the C++ compiler.

* sem_res.adb (Resolve_Actuals): If the formal is a class-wide
type conversion then do not skip resolving and expanding the
conversion; required to displace the pointer to the object and
reference the dispatch table associated with the target
interface type.
