Andreas Kling 25a5ed94d6 LibGC: Add GC::Weak<T> as an alternative to AK::WeakPtr<T> 
This is a weak pointer that integrates with the garbage collector.
It has a number of differences compared to AK::WeakPtr, including:

- The "control block" is allocated from a well-packed WeakBlock owned by
  the GC heap, not just a generic malloc allocation.

- Pointers to dead cells are nulled out by the garbage collector
  immediately before running destructors.

- It works on any GC::Cell derived type, meaning you don't have to
  inherit from AK::Weakable for the ability to be weakly referenced.

- The Weak always points to a control block, even when "null" (it then
  points to a null WeakImpl), which means one less null check when
  chasing pointers.
