tdf#147742 a11y: AccessibleGridControlBase: get accessible desc on demand

Previously, the accessible description was retrieved
in the `AccessibleGridControlBase` ctor and stored
in a class member. Change that to fetch the
description on demand.

`TableControl::GetAccessibleObjectDescription` is used
to get the description, which currently uses the row and
column index of the currently active cell.

When using the macro from the sample document in tdf#147742
with the Orca screen reader active, no cell was active
at the point that the ctor was called, so
`ROW_INVALID`/`COL_INVALID` were used, resulting
in a crash later (s. backtrace in tdf#147742).

If necessary, `TableControl::GetAccessibleObjectDescription`
could be extended to allow passing an explicit row/column index,
as is the case for `TableControl::GetAccessibleName`, then
override `AccessibleGridControlBase::getAccessibleDescription`
in `AccessibleGridControlCell`, similar to how it is done
for the accessible name in
