43574226 - [LV] Support EVL for partial reduction and VPExpressionRecipe. (#205741)

[LV] Support EVL for partial reduction and VPExpressionRecipe. (#205741) This patch adds the support for partial reduction with EVL tail-folding by not creating a new VPExpressionEVLRecipes but just changing the last expressionRecipes from VPReductionRecipe to VPReductionEVLRecipe. Currently, all partial reductions will be converted to VPExpressionRecipe when construction. So this patch also supports the VPExpressionRecipe for EVL.
