37ea0979 - [VPlan] Remove VPWidenRecipe constructor with no underlying instruction. NFCI (#166521)

[VPlan] Remove VPWidenRecipe constructor with no underlying instruction. NFCI (#166521) My understanding is that a VPWidenRecipe should be used for recipes with an exact underlying scalar instruction, and VPInstruction should be used elsewhere e.g. for instructions generated as a part of the vectorization process. The only user of the VPWidenRecipe constructor that doesn't take an underlying instruction is in adjustRecipesForReductions, but we can just use VPInstruction there.
