  [VPlan] Rename VPReverseVectorPointerRecipe to VPVectorEndPointerRecipe. NFC (#131086)

After #128718 lands there will be two ways of performing a reversed
widened memory access, either by performing a consecutive unit-stride
access and a reverse, or a strided access with a negative stride.

Even though both produce a reversed vector, only the former needs
VPReverseVectorPointerRecipe which computes a pointer to the last
element of each part. A strided reverse still needs a pointer to the
first element of each part so it will use VPVectorPointerRecipe.

This renames VPReverseVectorPointerRecipe to VPVectorEndPointerRecipe to
clarify that a reversed access may not necessarily need a pointer to the
last element.
