fix: save methods of children Date instance (#437)

[Oustinger]

Fix issue #437 by creating ClockDate as JS class and extending it from NativeDate

Why I did this way:

• In initinial solution (creating ClockDate by JS function) ClockDate can't be correct instance to extend from it. That's why I replaced function on class. And it resolved my problem.
• Mechanics of call Date() without new keyword I solved by using Proxy instance.
• Also in my solution removed an mirrorDateProperties function. It's not needed any more.

But I had some troubles with tests:

• I skiped this test, because I didn't understand what it checks and how it should be now
• I skiped an other test, because I think it's not corresponding for now. ClockDate.prototype never equals to Date.prototype, because ClockDate is extended from Date
• Please, check the other tests, that I changed. Hope, I changed them correct

Oooh, I somehow missed that this was added. Sorry about the late look, but while this is interesting, my head is a bit fried 🤯 This is quite a big change, so I (or someone else with a bigger head) needs to take a new look with a fresh head!

Thanks for providing a fix to something that bugged you a year ago. That's persistence we can appreciate 😄

It's a bit scary breaking change, so I think I would like some more 👀 on this before going ahead.

I started reviewing it and came to the "bit scary" conclusion as well.
