[ubsan] Replace AtomicElement with UB-safe alternative The previous AtomicElement wrapper fundamentally relied on reinterpret_casting a heap address to an instance of a C++ object, which is an invalid cast. This patch replaces that pattern with an ObjectSlot-based alternative that does not rely on UB.
