  -----------
  [VPlan] Use VPInstruction for VPScalarPHIRecipe. (NFCI) (#129767)

Now that all phi nodes manage their incoming blocks through the
VPlan-predecessors, there should be no need for having a dedicate
recipe, it should be sufficient to allow PHI opcodes in VPInstruction.

Follow-ups will also migrate VPWidenPHIRecipe and possibly others,
building on top of https://github.com/llvm/llvm-project/pull/129388.
