[VPlan] Replicate VPScalarIVStepsRecipe by VF outside replicate regions. (#170053) ...

Extend replicateByVF to also handle VPScalarIVStepsRecipe. To do so, the
patch adds a new lane operand to VPScalarIVStepsRecipe, which is only
added when replicating. This enables removing a number of lane 0
computations. The lane operand will also be used to explicitly replicate
replicate regions in a follow-up.
