  [VPlan] Add VPPhiAccessors to provide interface for phi recipes (NFC) (#129388)

Add a VPPhiAccessors class to provide interfaces to access incoming
values and blocks.

The first user is VPWidenPhiRecipe, with the other phi-like recipes
following soon.

This will also be used to verify def-use chains where users are phi-like
recipes, simplifying https://github.com/llvm/llvm-project/pull/124838.
