…provided by a default (#4719) ~~This PR is~~ This PR was part of a larger effort to standardize across the codebase our treatment of JS-specific value `undefined` as equivalent to absence of the value. - #4709 But then it turns out that because #4716 only applied to `coerceInputLiteral`, `coerceInputValue` only checked the post-coercion key number, so the distinction between omitted and undefined didn't matter. But there is a case where it does matter, if we choose to -- and we should -- fail coercion if a OneOf provides no keys but has a single default. This is an invalid case, as defaults are not allowed for OneOf, because they will all be filled in, but we should still fail coercion by checking the pre-coercion number of keys, which would be 0. And once we do that, we should treat undefined the same as omitted!
