Tomasz Grabiec b3728f7d9b utils: Introduce lsa::weak_ptr<> 
Simplifies managing non-owning references to LSA-managed objects. The
lsa::weak_ptr is a smart pointer which is not invalidated by LSA and
can be used safely in any allocator context. Dereferenced will always
give a valid reference.

This can be used as a building block for implementing cursors into
LSA-based caches.

Example simple use:

     // LSA-managed
     struct X : public lsa::weakly_referencable<X> {
         int value;
     };

     lsa::weak_ptr<X> x_ptr = with_allocator(region(), [] {
           X* x = current_allocator().construct<X>();
           return x->weak_from_this();
     });

     std::cout << x_ptr->value;
