  Log Message:
  -----------
  [VPlan] Keep start value of VPWidenPHIRecipe as VPValue.

Similar to D92129, update VPWidenPHIRecipe  to manage the start value as
VPValue. This allows adjusting the start value as a VPlan transform,
which will be used in a follow-up patch to support reductions during
epilogue vectorization.
