tdf#147742 a11y: AccessibleGridControl...: get accessible name on demand

Base class `AccessibleGridControlBase` was retrieving
an accessible name and storing it in class member 'm_aName'.

For the classes representing cells, derived from
`AccessibleGridControlCell`, the index is needed
to get a meaningful name, so the name retrieved in
the `AccessibleGridControlBase` ctor with hard-coded
row/column indices of 0 was replaced again in
the `AccessibleGridControlCell` ctor.

Replace that logic to just retrieve the name
on demand, and override
'getAccessibleName' in `AccessibleGridControlCell`
using the logic used in its ctor previously.

(No functional change intended here, but a
somewhat similar handling for the accessible
description was causing a crash when the Orca screen
reader was active. This will be handled in a following
commit.)
