Feature: #83350 - Add recursive filtering of arrays

See forge#83350


The new method \TYPO3\CMS\Core\Utility\ArrayUtility::filterRecursive() has been added as an enhancement to the PHP function array_filter() to filter multidimensional arrays.

The method ArrayUtility::filterRecursive() behaves just like array_filter() and if no callback is defined, values are removed if they equal to boolean false. See converting to boolean.


Arrays can be filtered recursive using the new method.
