Scoped (i.e.
local) object for temporarily replacing the current thread's tag stack with a different StackState.
This is typically used to bridge tag stacks in parallelism contexts. For example, a call site that spawns parallel tasks may capture its own tag stack state and pass it to the parallel tasks, that then use a StackOverride to ensure that memory allocations are billed to the same tags as the spawning thread. When StackOverride object is destroyed, the thread's previous tag stack is restored.
