9f5abd38 - [Codegen] Add a separate stack ID for scalable predicates (#142390)

[Codegen] Add a separate stack ID for scalable predicates (#142390) This splits out "ScalablePredicateVector" from the "ScalableVector" StackID this is primarily to allow easy differentiation between vectors and predicates (without inspecting instructions). This new stack ID is not used in many places yet, but will be used in a later patch to mark stack slots that are known to contain predicates.
