TreeTable: aria-level attribute not allowed

[TaneliTuomola]

Describe the bug

Aria-level attribute is supported with treegrid rows, but not table. Add missing roles to the treeTable html.
• The treegrid container has role treegrid.
• Each row container has role row and is either a DOM descendant of or owned by the treegrid element or an element with role rowgroup.
