Stephan Bergmann b512ce255f Make upcasting css::uno::Reference ctor require complete types 
The main reason for the "home-grown" UpCast introduced with
904b3d1fce "Up-cast conversion constructor for
css::uno::Reference" in 2013 was probably that we could not yet rely on C++11
std::is_base_of back then.  A (welcome) side effect was that the derived class
could be incomplete.

However, specializations of UpCast relying on whether or not T2 is incomplete
are obviously an ODR violation if the type is incomplete in some TUs and
complete (and derived from T1) in others.  And even if UpCast had internal
linkage, it would still be brittle that its behavior depends on the completeness
of T2 at the point of the template's instantiation, and not necessarily at the
point of use.

That means we should better base that ctor on std::is_base_of (which we can do
now since 39a1edd6fe "Make css::uno::Reference
upcast ctor LIBO_INTERNAL_ONLY"), which causes a compilation error at least on
Clang and GCC if the completeness requirements are not met.  This change fixes
all the cases where types need to be complete now, plus any resulting
loplugin:referencecasting warnings ("the source reference is already a subtype
of the destination reference").
