  -----------
  [VPlan] Use VPInstructionWithType for uniform casts. (#140623)

Use VPInstructionWithType instead of VPReplicate recipe for uniform
casts. This is a first step towards breaking up VPReplicateRecipe. Using
the general VPInstructionWithType has the additional benefit that we can
now apply a number of simplifications directly.
