tdf#150683 qt a11y: Add bound checks for table methods

Since the row/column indices come from outside
(usually from assistive technology like a screen reader),
validate them before using them when calling the
corresponding methods on the
XAccessibleTable{,Selection} interfaces.

Otherwise, calling the corresponding UNO methods will
result in a crash due to an `IndexOutOfBoundsException`
being thrown.
