tdf158030 sc a11y: Report cell coords via {row,col}indextext obj attr
to the corresponding gtk a11y relations.
Together with a suggested MR for gtk [1] to add the
corresponding mapping to AT-SPI2 there, following
the Core Accessibility API Mappings specification [2],
this makes these available on the AT-SPI2 layer.
Interacting with Calc cells e.g. in Accerciser currently
doesn't really work though, because LibreOffice freezes
due to the Gtk implemenation of "GetChildCount" currently
trying to iterate over all children, s. Gtk issue [3].
(Tested by hard-coding dummy values for a Writer paragraph
in `SwAccessibleParagraph::getExtendedAttributes` instead.)
