tdf#123864 a11y: Add new AccessibleStateType::CHECKABLE

for `VCLXAccessibleMenuItem`.

`MenuItemData::HasCheck` looks like it already provides
what's needed to say whether an item is checkable, therefore
add a `Menu::IsItemCheckable` that makes use of this and
and a `VCLXAccessibleMenuItem::IsCheckable` that
makes use of that in turn.

Extend `VCLXAccessibleMenuItem::FillAccessibleStateSet` to
use the latter to report the CHECKABLE state accordingly.
