tdf#100086 tdf#124832 wina11y: Implement IAccessibleTableCell
Add a new class 'AccTableCell' that implements the
IAccessibleTableCell interface from the IAccessible2 spec
and add what's needed to expose it to accessibility tools
via COM.
Since there's no specific XInterface for table cells
that an XAccessible's context could be queried for,
make use of the fact that a table cell's
parent is a table, i.e. its accessible context implements
XAccessibleTable.
AccTableCell keeps a reference to that table and remembers the
cell's index in the parent to retrieve information
on the cell from there.
This addresses the
> At least for LibreOffice Table Cells don't implement
> IAccessibleTableCell, and therefore there's no way to get the row and
> column span. LibreOffice itself also does not expose the merged state in
> the accessible name of the cell.
comment from [1] (which is the NVDA counterpart for LO's
tdf#124832) and may also help for tdf#100086,
though more work will be needed on LibreOffice and/or NVDA
side for both issues.

tdf#100086 tdf#124832 wina11y: Implement IAccessibleTable2
Extend 'CAccTable' to implement the 'IAccessibleTable2'
interface in addition to the (deprecated)
'IAccessibleTable' interface from the IAccessible2 spec.
'IAccessibleTable2::get_cellAt' and
'IAccessibleTable2:get_nSelectedCells' are basically
the same as 'IAccessibleTable::get_accessibleAt' and
'IAccessibleTable::get_nSelectedChildren' under
new names.
'IAccessibleTable2::get_selectedRows' and
'IAccessibleTable2::getSelectedColumns' are
essentially the same as their 'IAccessibleTable'
counterparts, except that they have the first
param removed (which is ignored in the
IAccessibleTable version anyway).
'IAccessibleTable2::get_selectedCells' is similar
to 'IAccessibleTable::get_selectedChildren', but
returns an array of references to selected cells,
while the latter just returns an array of their
indices.
Note: Just having the IAccessibleTable2 interface,
but not the IAccessibleTableCell one implemented makes
the experience when using the NVDA screen reader
temporarily worse, e.g. it now only says "selected" instead of
the name of the currently focused cell in Calc.
Implementation of IAccessibleTableCell is added
in an upcoming commit
(Change-Id: I0f53212d14ee17c760b9e6c91be2154a1b25d862,
"tdf#100086 tdf#124832 wina11y: Implement IAccessibleTableCell")
and makes NVDA announce the name of the cell again.
