[Rector] Add rector to require-dev and use single autoload vendor for run PHPUnit

[samsonasik]

@nikophil since the approved solution is the patch on rector bootstrap, the only way to work on your use case on this repo is use rector/rector on your require-dev, and remove the autoload of rector autoload, since it already loaded early.

@samsonasik Seems "Static analysis" job needs path update

[samsonasik]

@TomasVotruba sure 👍 , updated phpstan paths at next commits cba0b34 and 1b1b5ad

@nikophil MakeFactoryTest seems flip flop change lookup directory tools, I guess you can take care the rest from here :)

I think that we also need to remove ./tools/bin/rector

I'll do this in a further PR.

thanks a lot for your help 👍
