colexec: projection operators do not support NULL as a constant argument #41001

As Rafi noticed here https://github.com/cockroachdb/cockroach/pull/40927#pullrequestreview-292024506, projection operators do not support having NULL as a constant argument. At the moment, all such cases we'll be rejected by the vectorized engine because of https://github.com/cockroachdb/cockroach/blob/master/pkg/sql/colexec/execplan.go#L1096, so it is not a high priority bug, but we should fix it at some point.
