Allow to check specific TYPO3 Upgrade parts / Versions

Currently all sniffs and configs will be applied.

Still it's possible to configure the configuration folders / globing. We have to check whether that's enough, and provide ready to use phpcs.xml.dist / ruleset.xml files for each TYPO3 version. So you can use different PHPCS Standards.

Another solution might be the same way as done by https://github.com/wimg/PHPCompatibility#using-the-compatibility-sniffs using a runtime-set to define the versions.
