  [VPlan] Fix vplan printing for VPExpressionRecipe w/conditional reduction. (#198954)

This patch contains two parts.

- Add a new vplan-printing test which is duplicated from
vplan-printing-reductions.ll and force tail folding.
- Fix the printing of VPExpressionRecipe for conditional reductions.
Since the mask operand cannot be accessed directly through the reduction
recipe once folded, it need to be fetched from the expression recipe's
operands.
