Internal `getSyclObjImpl` API is exposed to users via ADL

#include <sycl/sycl.hpp>

int main() {
    sycl::device d;
    auto id = getSyclObjImpl(d);
    sycl::queue q;
    auto iq = getSyclObjImpl(q);
}

compiles while it shouldn't. I think this is due to the inheritance from detail::OwnerLessBase.
