[VPlan] Use StepVector without operands, VPBuilder in C++ tests (NFC) (#208075) Update unit tests construction VScale for VPInstructions without operands to use StepVector where possible. When VScale is needed, construct with VPBuilder. Also update constructing other recipes in same function to use VPBuilder, for consistency.
