Previously, null/undefined were removed upfront, which is incorrect. Now nullable types are removed with other non-primitives after union is lifted over spread. This produces unions, which are larger, but more correct.

Fixes #13066
Previously, null/undefined were removed upfront, which is incorrect. Now nullable types are removed with other non-primitives after union is lifted over spread. This produces unions, which are larger, but more correct.
Also move some spread tests into the conformance suite.
