Make upcasting css::uno::Reference ctor require complete types
The main reason for the "home-grown" UpCast introduced with 904b3d1fceee5827076758ed2a81f80cb73493ca "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 39a1edd6fec902ef378acce8af42c4d7fba280d0 "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").
