[DAG] SimplifyDemandedBits - correctly adjust truncated shift amount type

As noticed on D56387, for vectors we must always correctly adjust the shift amount type during truncation (not just after legalization). We were getting away with it as we currently only accepted scalars via the dyn_cast<ConstantSDNode>.
