Make Map constructor argument optional and nullable (#43396) ...

* Make Iterable Map constructor argument optional

Fixes #37779

* Change Map constructor in iterable to accept both null and undefined.

According to the spec (https://tc39.es/ecma262/#sec-map-iterable), the sole argument passed to Map is allowed to be null or undefined.

* Changed Map constructor to ensure new Map() still types as Map<any, any>.

* Add map constructor test.

This proves that the previous commit fixes #37779, as well as that new Map() still types as Map<any, any>.

* Update baseline.
