Feature: #90347 - Enable recursive transformation of properties in JsonView

Description

The Extbase \TYPO3\CMS\Extbase\Mvc\View\JsonView is now able to resolve recursive properties of objects, e.g. directories containing directories or comments containing comments as replies.

Examples:

1. This is for 1:1 relations, where a comment has at most 1 comment.

$configuration = [
    'comment' => [
        '_recursive' => ['comment']
     ]
];

2. This is for the more common 1:n relation in which you have lists of sub objects.

$configuration = [
    'directories' => [
        '_descendAll' => [
            '_recursive' => ['directories']
        ],
    ]
];

You can put all the other configuration like _only or _exclude at the same level as _recursive and the view will apply this for all levels.

Impact

Developers can now use the _recursive property in the JsonView configuration in order to resolve recursive properties instead of defining each level manually.
