[VPlan] Remove ILV::sinkScalarOperands. (#136023) 
Remove legacy ILV sinkScalarOperands, which is superseded by the
sinkScalarOperands VPlan transforms.

There are a few cases that aren't handled by VPlan's sinkScalarOperands,
because the recipes doesn't support replicating. Those are pointer
inductions and blends.

We could probably improve this further, by allowing replication for more
recipes, but I don't think the extra complexity is warranted.

Depends on https://github.com/llvm/llvm-project/pull/136021.
