iconchoicectrl a11y: Reuse parent handling + disposing from base class

Drop the custom handling for the accessible parent
from AccessibleIconChoiceCtrl, as the base class
VCLXAccessibleComponent already has an implementation
for vcl::Window subclasses that effectively does the same.

Drop AccessibleIconChoiceCtrl::disposing, which also
means that the base class one is used now, which
so far wasn't called from the override for no apparent
reason.
