Feature: #93197 - Resolve collection types of non-persistent objects

See Issue #93197

Description

Collection types are used to define a specific class that should be within Extbase’s \TYPO3\CMS\Extbase\Persistence\ObjectStorage class.

Example:

/**
 * @param ObjectStorage<Item> $items
 */
public function setItems(ObjectStorage $items): void
{
    $this->items = $items;
}

These docblocks are analyzed so the PropertyMapper knows how to map incoming requests. This mapping already works for persistent objects (domain models). As non-persistent objects are also used for property mapping, namely DTOs (data transfer objects), this now works for them, too.

Impact

Developers can use collection types in docblock annotations for non-persistent objects. The collection type is considered while property mapping requests.
