[Scoper] Make phpstan/phpdoc-parser part of preload.php and preload-split-package.php

[samsonasik]

This PR make phpstan/phpdoc-parser part of preload.php, so it loaded early by default when run rector, so no need to make part of conflict config:

    "conflict": {
-        "phpstan/phpdoc-parser": "<1.7",

All checks have passed 🎉 @TomasVotruba it is ready for review.

Could you elaborate more on what was the issue here?

For example, I want to run rector on laminas components that has require-dev laminas/laminas-coding-standard that require slevomat/coding-standard:7.2.1 that uses phpstan/phpdoc-parser ^1.5.1, that make installing rector cause error:

composer require --dev rector/rector
Info from https://repo.packagist.org: #StandWithUkraine
Using version ^0.14.2 for rector/rector
./composer.json has been updated
Running composer update rector/rector
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laminas/laminas-coding-standard is locked to version 2.4.0 and an update of this package was not requested.
    - slevomat/coding-standard 7.2.1 requires phpstan/phpdoc-parser ^1.5.1 -> satisfiable by phpstan/phpdoc-parser[1.5.1].
    - rector/rector 0.14.2 conflicts with phpstan/phpdoc-parser <1.7.
    - laminas/laminas-coding-standard 2.4.0 requires slevomat/coding-standard ^7.0 -> satisfiable by slevomat/coding-standard[7.2.1].
    - Root composer.json requires rector/rector ^0.14.2 -> satisfiable by rector/rector[0.14.2].

Running rector from global will make error as well as different __construct() params:

rector process 
PHP Fatal error:  Uncaught _PHPStan_9a6ded56a\Nette\DI\ServiceCreationException: Service of type PHPStan\PhpDocParser\Parser\PhpDocParser: Unable to pass specified arguments to PhpDocParser::__construct(). in phar:///Users/samsonasik/.composer/vendor/rector/rector/vendor/phpstan/phpstan/phpstan.phar/vendor/nette/di/src/DI/Resolver.php:421

The workaround was to:

1. Remove temporary laminas/laminas-coding-standard
2. Require-dev rector
3. Run Rector
4. Remove rector
5. add back laminas/laminas-coding-standard

But I think make it part on preload.php should solve it.

By add this to preload, Rector should use the phpstan/phpdoc-parser from scoped vendor, while original laminas/laminas-coding-standard will use old phpstan/phpdoc-parser.

I see. That makes sense 👍
