[llvm] [NFC][Scalarizer][TargetTransformInfo] Add `isVectorIntrinsicWithOverloadTypeAtArg` api (PR #114849)

This feels like a partial change which leaves us in an odd state.

Instead of cleaning up all the uses of the VectorUtils `isVectorIntrinsicWithOverloadTypeAtArg`, you only updated the uses in the Scalarizer, which in turn makes the Scalarizer's implementation a bit odd.
