The AT-SPI TableCell interface's GetColumnHeaderCells
and GetRowHeaderCells methods were not documented in
the XML specification until recently, but are actively used,
e.g. also by the Orca screen reader since commit
ac2c4470ff
("Prefer table cell interface for getting row and column headers").
5145d3899d only implemented
the TableCell methods that were contained in the XML spec
by then.
Handle these two methods as well, and add an explicit
warning for the case an unknown method is called.

AT-SPI TableCell XML spec:
