AK: Make WeakPtr<T>::value() return NonnullRefPtr<T>

Browse source 
This API is only used by Jakt to implement weak reference unwrapping.
By making it return a NonnullRefPtr, it can be assigned to anything
that accepts a NonnullRefPtr, unlike the previous T* return type (since
that can also be null).
