[Tree] Allow multiple order critieria in reorder and reorderAll

[Waigie]

The functions \Gedmo\Tree\Entity\Repository\NestedTreeRepository::reorder and \Gedmo\Tree\Entity\Repository\NestedTreeRepository::reorderAll both take the parameters $sortByField and $direction with the type ?string. By allowing string arrays as well, the functions allow reordering with multiple order criteria (e.g. sort by category and date).
