Michael Weghorn dd5f021e08 tdf#150683 gtk3 a11y: Expose AtkTableCell interface for cells
While LO doesn't have any UNO a11y interface
for table cells, the methods for the `AtkTableCell`
interface can be implemented by using the methods
from the `XAccessibleTable` interface of the table
(which is the parent of the cell), similar to
the way this was impemented for winaccessibility
and the qt5/qt6/kf5 VCL plugins in

        qt5 a11y: Implement QAccessibleTableCellInterface

With this and the Orca commit to make use of the AT-SPI
TableCell interface to query the position for a cell [1],
announcing selected cells that have a cell/child index
that doesn't fit into 32 bit now also works for the
gtk3 VCL plugin, see the full commit message of

        [API CHANGE] tdf#150683 a11y: Switch a11y child index to 64 bit

for more background information.

In a quick test with Accerciser and the gtk3 VCL plugin
as follows, the output looked as expected:

1) start LO Writer, "Table" -> "Insert Table"
2) select to create table with  2 rows, 2 columns
3) make sure "Heading" is checked, "Heading rows": 1
4) "Insert"
5) in the first row, type "First heading" into first column,
   "Second heading" into second column
5) start Accerciser
7) select the table cell element "A2" in Accerciser's treeview of the a11y
   hierarchy (which refers to the table cell in the second row, first column)
8) type these in Accerciser's IPython console:

    In [1]: acc.queryTableCell()
    Out[1]: <pyatspi.tablecell.TableCell at 0x7fa17cf2b550>
    In [2]: acc.queryTableCell().position
    Out[2]: (1, row=1, column=0)
    In [3]: acc.queryTableCell().rowSpan
    Out[3]: 1
    In [4]: acc.queryTableCell().columnSpan
    Out[4]: 1
    In [5]: acc.queryTableCell().get_table()
    Out[5]: <Atspi.Accessible object at 0x7fa17cf975c0 (AtspiAccessible at 0x55bfe77b4e10)>
    In [6]: acc.queryTableCell().get_table().name
    Out[6]: 'Table1-1'
    In [7]: acc.queryTableCell().get_columnHeaderCells()[0]
    Out[7]: <Atspi.Accessible object at 0x7fa17d2e7b00 (AtspiAccessible at 0x55bfe77ab240)>
    In [8]: acc.queryTableCell().get_columnHeaderCells()[0].name
    Out[8]: 'A1'
