Breaking: #98069 - DebugConsole removed

See forge#98069


The DebugConsole comes from ExtJS times and was triggered when e.g. a request failed to give a developer its response, including the stacktrace. Nowadays, browsers offer a console allowing to investigate requests. Also, PHP debuggers (e.g. xdebug) are commonly known and used, which makes the DebugConsole obsolete.


Triggering the DebugConsole is not possible anymore. Also, the PHP method \TYPO3\CMS\Core\Utility\DebugUtility::debug() always renders the plain debug output to the client.

The 3rd argument $group of the method \TYPO3\CMS\Core\Utility\DebugUtility::debug() is removed.
