Important: #78650 - TypoScriptService class moved from Extbase to Core

See forge#78650


The PHP class TypoScriptService has been moved to the core extension, as it has no direct link to Extbase, and a lot of other system extensions are using the class.

The old class name TYPO3\CMS\Extbase\Service\TypoScriptService is registered as a class alias for the new class name TYPO3\CMS\Core\TypoScript\TypoScriptService, so extensions can call the class via the Extbase PHP namespace in TYPO3 v8 without any downsides.
