[repacker] make repacker object ids stable.
Prior to this change the object id for a vertex in the repacker graph is it's position in the topological ordering. As a result after each sorting the object ids change. This decouples the topological sorting from the object id assignments. A separate ordering list is retained. This simplifies handling around object ids which no longer needs to account for them shifting, and improves performance by eliminating the step of reassigned link object ids after each sort.

Fix invalid reinterpret_cast (#5558)
* Fix invalid reinterpret_cast
reinterpret_cast from non-atomic object to atomic object is not valid.
https://eel.is/c++draft/atomics.types.generic#general-3
>[Note 2: The representation of an atomic specialization
>need not have the same size and alignment requirement as
>its corresponding argument type. — end note]
https://eel.is/c++draft/basic.compound#5
>5 Two objects a and b are pointer-interconvertible if
>(5.1) they are the same object, or
>(5.2) one is a union object and the other is a non-static
>data member of that object ([class.union]), or
>(5.3) one is a standard-layout class object and the other

objects of types `int` and `std::atomic<int>` are not
pointer-interconvertible (an object of type `int` is not
first non-static data member of `std::atomic<int>`)
https://eel.is/c++draft/basic.lval#11
>11 An object of dynamic type T-obj is type-accessible through
>a glvalue of type T-ref if T-ref is similar ([conv.qual]) to:
>(11.1) T-obj,
>(11.2) a type that is the signed or unsigned type corresponding
>to T-obj, or
>(11.3) a char, unsigned char, or std::byte type.
>If a program attempts to access ([defns.access]) the stored
>value of an object through a glvalue through which it is not
>type-accessible, the behavior is undefined
The original code resulted in undefined behavior.
* revert code formatting
* fix const qualifier in type for atomic operation.
* implement copy and move ctors (assignment-operators) and swap functions.
* swap-functions replaced as frendly members, common header includes returned.
* add HB_ prefix to defined macro.
* some formatting.
