[VPlan] Support VPWidenSelectRecipe in narrowToSingleScalar.
VPWidenSelectRecipes are single scalars if all their operands are. Add
support for narrowing them to a single scalar VPReplicateRecipe.
This fixes a crash after
https://github.com/llvm/llvm-project/pull/142433 (aa24029319083) when
due to a replicate recipe not being converted to single-scalar being
hoisted to the vector preheader.
