[Alternative] Add EnumCaseToPascalCaseRector with use of DynamicSourceLocatorProvider

[samsonasik]

@marcelthole here I cherry-picked your commits from PR:

• Add rule for converting Enum cases to PascalCase naming #6890

as an alternative PR, this utilize DynamicSourceLocatorProvider which verify target is on the Reflector which use of paths defined in configuration.

The StatusEnum needs to be moved to Source so it marked as "outside" Fixture so be skipped from change.
This on unit test, I add includeFixtureDirectoryAsSource flag so defined PHP classes in Fixture directory can be load when set.

Closes #6890

@marcelthole @boesing I added failing new test for use of ->withAutoloadPaths()

80a0d0b#diff-9c0f8fca70b157b9f8b24c57101088a00f86f370940d68c4d595544d5dee22ff

as withAutoloadPaths() adds to DynamicSourceLocatorDecorator, use of DynamicSourceLocatorDecorator become invalid, it seems it needs to check on paths as fallback

[samsonasik]

Fixed with verify that target path is part of autoload paths as fallback 9ac254c

@marcelthole @boesing I talked with @TomasVotruba today, and it is ok to merge it as is :)

This rule is not part of any set, so after the merge, you can try dev-main:

composer config minimum-stability dev
composer config prefer-stable true
composer update rector/rector:dev-main

and register manually:

<?php

declare(strict_types=1);

use Rector\CodingStyle\Rector\Enum_\EnumCaseToPascalCaseRector;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
     // other config here...
    ->withRules([EnumCaseToPascalCaseRector::class]);
