Js constructor function fixes (#22721)
* Do not add undefined for this assignments in functions

* Test:constructor functions with --strict

* First draft -- works, but needs a stricter check added

* Update baselines

* Make undefined-skip stricter and more efficient

Symbol-based now instead of syntactic

* Exclude prototype function assignments

* Add explanatory comment
