ValueSerializer: Distinguish between 'undefined' and an absent property. Dealing with this case requires a wire format change. It is possible that an element can be absent even in an array where the dense format was chosen (because the array initially had no holes), if the elements are modified while they are being serialized. In this case, a new tag for the "hole" is emitted. The logic to treat undefined in dense arrays as an absent property is restricted to versions of the wire format that this tag did not exist.
