Introduce stack snapshotting / cloning (#18741)
Add `StackSnapshot#` primitive type that represents a cloned stack (StgStack).
The cloning interface consists of two functions, that clone either the treads
own stack (cloneMyStack) or another threads stack (cloneThreadStack).
The stack snapshot is offline/cold, i.e. it isn't evaluated any further. This is
useful for analyses as it prevents concurrent modifications.
For technical details, please see Note [Stack Cloning].
