A list view should always expose a table with a single column to
accessibility tools even if the underlying model has multiple columns.
Several functions need to be changed so that they only consider the
model column that was set on the list view.
For a list view logicalIndex() must only consider indexes for the
model column. For valid indexes the logical index is simply the row
because list views have neither row headers nor column headers.
The column count for list views is always 1 (unless the model has no
columns). The child count needs to use the column count of the
accessible table instead of the column count of the underlying model.
child(), cellAt(), selectedCellCount(), and selectedCells() get
separate implementation for list views.
