[PHP 8.0] Add SetStateToStaticRector

[simivar]

Part of #4765. I didn't use ChangeMethodVisibilityRector as it required a class name to be specified and this one should be a generic one.

A way to use generic ChangeMethodVisibilityRector could be to refactor it to not require class name but I don't know if that's a visible solution for you.

@TomasVotruba I might need some guidance on how to make it work with PHP 8 tests.

[TomasVotruba]

I'd skip the test on PHP 8, as the code is not PHP 8 compatible.

Something like:

@requires PHP < 8

I didn't use ChangeMethodVisibilityRector as it required a class name to be specified and this one should be a generic one.

That's probably a good choice... I wonder, would this doo?

[stdClass::class, '__set_state', 'static']

AFAIK, stdClass is implicit parent of any class.

Ah, it doesn't seem to work: https://3v4l.org/7RJ0X
